The United States Senate preserves Margaret Chase Smith’s Declaration of Conscience on its own website. Seventy-six years later, much of the conduct she condemned remains in active use. The archive is in better condition than the conscience.
That is a judgment about public power, with consequences beyond the chamber’s wounded sense of dignity. When accusations substitute for evidence, when a witness becomes a target, when loyalty to a party excuses a failure of duty, the people outside the institution pay for what the people inside it permit.
On Election Day, the appropriate response is to use the authority that still belongs to us. My recommendation today is plain: vote for Democrats. The Republican conduct examined here gives voters substantial reason to deny that party further power. Democrats should receive that vote as a demand for accountable government, never as a certificate of innocence.
Smith’s speech helps explain the distinction.
A Republican talking to Republicans
On June 1, 1950, the Republican senator from Maine rose to confront the Red Scare politics associated with a fellow Republican, Joseph McCarthy. She did not name him. She did identify what was happening to the institution they both served: a deliberative body was becoming “a forum of hate and character assassination.” Read the Senate’s historical account.
Her complaint went well beyond incivility. Smith described senators using the protection of their offices to damage outsiders while observing elaborate rules against insulting one another. The chamber guarded its members’ dignity more carefully than the reputations of the citizens it could injure.
She named four rights: to criticize, to hold unpopular beliefs, to protest and to think independently. Exercising those rights, she argued, should not cost an American a livelihood or a reputation. Neither should knowing somebody whose opinions were unpopular. The complete speech is preserved by the Senate.
This was a Republican’s rebuke of Republican methods. Smith wanted her party to win. She sharply criticized the Democratic administration’s leadership and spending. She believed Republicans had ample grounds for opposition without manufacturing accusations or exploiting fear. Six other Republican senators joined her declaration.
That context gives the speech its force. She was willing to tell her own side that victory could become a national defeat if the means of obtaining it destroyed political integrity.
The phrase for which she is remembered was a warning against the “Four Horsemen of Calumny”: fear, ignorance, bigotry and smear. Those horses have had a long working life.

The old machinery still works
Qoheleth’s observation in Ecclesiastes, that there is nothing new under the sun, is a useful warning against political amnesia. So is the familiar saying that history rhymes. Neither requires us to pretend that 1950 and 2026 are identical.
The Cold War setting was specific. The political machinery Smith described is recognizable across eras: inflate suspicion into certainty, turn disagreement into a test of loyalty, make independent thought costly, and persuade decent people that their side’s misconduct must be tolerated because the other side is worse.
Her speech also disposes of the comforting idea that the Senate was uniformly honorable until our own unfortunate generation arrived. She had to make that argument in 1950 because senators were failing those standards in 1950. Institutions do not become trustworthy merely by getting old. Their members have to practice restraint, accept scrutiny and refuse useful lies.
The recent record contains failures concrete enough to judge without inventing anybody’s motives.
A hearing room is not a fight club
At a Senate Health, Education, Labor and Pensions Committee hearing on November 14, 2023, then-Sen. Markwayne Mullin, an Oklahoma Republican, confronted Teamsters president Sean O’Brien over O’Brien’s earlier social-media taunts. Mullin challenged him to settle the matter physically and said, “Well, stand your butt up, then.” O’Brien verbally accepted the challenge. Chairman Bernie Sanders intervened. No fistfight occurred. The exchange is in the official hearing transcript, printed page 55.
“You are a United States Senator,” Sanders reminded Mullin. Later in the exchange, Mullin told O’Brien, “I don’t care about respecting you at all.”
Precisely. The office carries an obligation to control one’s conduct, especially while exercising power over a witness appearing before a committee. A witness’s provocation does not relieve a senator of that obligation. Americans taking time away from work to address a public body, in Augusta or anywhere else, should not have to wonder whether an official considers a personal insult grounds for a physical confrontation.
Smith warned about the use of public office as a platform for irresponsible sensationalism. A Senate hearing turned into a proposed fight supplies a remarkably literal illustration.
Nor did the episode prevent a later grant of greater authority. On March 23, 2026, the Senate confirmed Mullin as secretary of homeland security, 54–45. Democrats John Fetterman and Martin Heinrich joined the Republican votes for confirmation. Their votes are part of the record, too. In my judgment, a willingness to threaten a hearing-room confrontation should weigh heavily against entrusting somebody with an office that exercises the government’s coercive power. That judgment applies to the Democrats who helped confirm him as well as to the Republicans.
What the votes recorded
The more serious failures are recorded in roll calls.
On the night of January 6, 2021, after the attack on the Capitol, six Republican senators voted to sustain an objection to counting Arizona’s electoral votes. Ted Cruz and Josh Hawley were among them. The Senate rejected the objection, 93–6. That is the Senate’s own record.
An objection was a procedure the law allowed. Its availability does not make its use responsible. My judgment is that attempting to reject a state’s electoral votes on that night, after the country had seen where the campaign against the election result had led, was a profound failure of public duty. A senator’s responsibility includes knowing when to stop lending institutional weight to a destructive cause.
On February 13, 2021, the Senate voted 57–43 to find Donald Trump guilty in his second impeachment trial. Because conviction required a two-thirds majority, he was acquitted. Seven Republicans voted guilty. Their votes matter: the record does not support the easy claim that no Republican showed courage or that every senator made the same choice. See the complete roll call.
Mitch McConnell voted not guilty. Afterward, he said Trump was “practically and morally responsible for provoking the events of the day.” McConnell’s stated reason for acquittal was constitutional: he believed a former president was beyond the Senate’s power to convict. That explanation belongs in any honest account of his vote. His full remarks appear in the Congressional Record.
It does not place his judgment beyond criticism. A Senate capable of describing a president’s responsibility in those terms, yet unable to assemble the votes for conviction, demonstrated the distance between recognizing a failure and imposing a consequence. The seven Republican votes for guilt showed that acquittal was a choice, not a position every Republican regarded as constitutionally unavoidable.
Smith’s standard asks what loyalty costs the country. The question remains even when a senator can deliver an eloquent explanation afterward.
The standard has to survive our own side
An endorsement of Democrats cannot honestly depend on pretending Democrats are incapable of corruption.
Robert Menendez, who served New Jersey as a Democrat, was convicted by a federal jury on July 16, 2024, of offenses including bribery and acting as a foreign agent. On January 29, 2025, he was sentenced to 11 years in prison. These were a jury verdict and a sentence, not merely somebody’s accusation. The Justice Department records the conviction and sentence.
There is no principled version of this argument in which a Democratic label disinfects that conduct. A party that asks for votes in the name of public integrity must accept investigation, evidence and consequences when its own people fail. Smith insisted on that obligation while criticizing her own party. Democrats deserve the same demand.
Applying a common standard does not require manufacturing an equal score for unequal events. A bribery conviction, a threatened fight, an electoral objection and an impeachment vote are different acts. They should be described accurately and judged for what each reveals about the use of power.
A vote with conditions
I am not claiming to know how Margaret Chase Smith would vote in 2026. She spoke for herself in 1950. Her speech is available in full precisely so readers can see her politics, her language and her argument rather than accept a convenient modern reconstruction.
My conclusion is my own. The record of Republican indulgence of intimidation and failures of accountability warrants a change in political power. Voting for Democrats today is a practical way to demand that change.
It is also the beginning of an obligation. The people elected with those votes must be challenged when they dodge scrutiny, protect corruption or turn a citizen into a prop. A conscience that activates only when the other party misbehaves is a party instrument.
The Senate has had Smith’s words for 76 years. It has had ample time to learn that dignity is earned in the exercise of power, particularly when restraint is inconvenient and the person who needs protection is somebody the powerful dislike.
Vote for Democrats today. Then hold them to the standard that made a Republican’s speech worth remembering.
