A blue wave in November could be the end of President Trump's presidency, according to Rep. Sean Duffy, R-Wis.

In a Friday interview with Milwaukee-area radio host Dan O'Donnell, Duffy said his colleagues on the other side of the aisle would eagerly move to impeach Trump should they take back the majority in the fall — though they may play it coy during campaign season.

"Democrat candidates might be sketchy about admitting that, especially in more 50-50 seats, but of course they're going to impeach Donald Trump," the four-term Wisconsin Republican said. "Do you think that MSNBC or CNN would allow for anything less?" he continued, arguing the Democratic Party's shift leftward means their caucus is even more inclined to pursue impeachment.

"There aren't that many Blue Dog Democrats left in Congress," Duffy contended. "They are radical leftist, socialist Democrats. They are like Nancy Pelosi. They are far-left people."

"That's who's winning their primaries, and do you think that the far-left 'Resist' movement base of the Democrat Party would accept anything other than impeachment?" the congressman asked.

It's early, but the prospect of impeachment has not received much attention as midterm races heat up around the country, though that's clearly what's on the line in November. Before he had even completed one year in office, Democrats had already introduced resolutions to impeach the president. Fifty-eight of them voted in December to open debate on Rep. Al Green's, D-Texas, impeachment bill.

For centrist Democrats in Trump-friendly districts fighting the pull to align with the party's progressive wing, confronting the question of whether they're open to impeaching Trump could be complicated. Evidence has emerged (even in Wisconsin) to suggest an enthusiasm gap between Democrats, excited to obstruct Trump, and Republicans, apathetic about their party's work in Washington, could spell trouble for the GOP. Raising the stakes by amplifying the threat of impeachment from now until November could help the GOP rally voters to turn out on Election Day.
