This is actually what a colleague of mine predicted on Monday: Trump will win the election, but Congress is gonna impeach him after a year or so. I thought it unlikely that Trump would win, so maybe its time to reconsider my colleague's wisdom.
Are there enoug votes? If you thrown in all Democrats with the NeverTrump Republicans... possibly. All they need is a sufficient pretext. And they would probably wait until his approval ratings have dropped and he's unpopular enough. But all things considered, a Andrew Johnson-like scenario is more likely than ever.
