"Any member of Congress is capable at any time of doing harm to his or her political party or even the country itself.
"Casting a vote undermining a carefully crafted piece of legislation after committing to colleagues not to do so. Making a public statement clearly at odds with universally accepted norms. Engaging in conduct that is unlawful, unethical, or both. Refusing to apologize when such an act clearly is necessary and appropriate. These are but a few actions in which a senator or member of Congress can engage that can hurt their party colleagues or, in extreme cases, the country.
"Rarely, however, can someone in as important a position as a sitting United States senator do such great harm as that by Arizona’s Sen. Jeff Flake in telling his Republican Party, and indeed the entire country, that he would refuse to vote to confirm Judge Brett Kavanaugh on the floor of the Senate — even after voting to have the nomination reported favorably by the Judiciary Committee on which he serves — unless the FBI conducts another investigation; this one focused on the allegations leveled against Kavanaugh after the week-long hearings conducted by the committee earlier this month." . . .
