Here, we’re in uncharted territory. There has never before been an impeached president on the ballot seeking re-election. Andrew Johnson didn’t get his party’s nomination in 1868. Bill Clinton was in his second term when he was impeached, so he couldn’t run in 2000. But President Trump is expected to be the Republican nominee in November.
“This is not a gold star in the history books,” says Larry Sabato of the Center for Politics at the University of Virginia. “But I’m not sure how much effect it’s going to have on the election. Everybody already knows who they’re voting for.”
So far, Trump’s base of supporters hasn’t been swayed by the revelations of the impeachment inquiry or the vote itself. But the president’s approval rating has hovered around 40 percent for most of his presidency, so he might need to reach beyond his base to win in November.
And if the impeachment hasn’t swayed Trump’s core supporters, there’s little doubt that it has fired up his opponents. “Impeachment will energize the Democratic base, and that’s going to increase turnout,” Sabato says. “Turnout is going to break all records.”
