But there's another possibility.
In my experience, most elected politicians have two goals -- to do what they consider to be the right things for the American public, and to be reelected (not necessarily in that order).
If Trump's poll numbers continue to plummet -- particularly among Republicans and Independents -- twenty-two House Republicans may well decide their chances for being reelected are better if they abandon him before the 2018 midterms.
Paul Ryan and the House Republican leadership might make a similar calculation, at least enough to put a bill of impeachment on the table.
Most House Republicans prefer Vice President Mike Pence to Donald Trump anyway. As one said to me several months ago, "Pence is a predictable conservative. Trump is an unpredictable egomaniac. Most of us are more comfortable with the former."
There's a good chance Trump's polls will continue to fall. First, he's shown to be his own worst enemy. Even when things are going reasonably well, he seems bizarrely intent on stirring controversy -- and saying or tweeting things that get him into trouble.
There's also a matter of the economy. The expansion that began in 2009 is getting long in the tooth. If history is any guide, we're due for a slowdown or recession. And justified or not, presidents get blamed when Americans lose jobs.
Donald Trump doesn't have the character or the temperament to be president of the United States. But this obvious fact isn't enough to get him fired.
He'll be fired when enough Americans decide they can't abide him anymore.
Then, maybe in an impeachment proceeding, it will come out that Trump did something incredibly stupid -- like give a nod of approval to one of his campaign bottom feeders like Roger Stone to tell a Russian operative to go ahead with their plan to interfere in the 2016 election.
The House impeaches. The Senate convicts. That's the end of Trump.
