It already moved the needle when it comes to public support for impeachment far more than the Mueller report ever did. Impeachment basically went overnight from quite unpopular to just about evenly popular. Obviously Trump isn't going to get impeached by the senate unless things get much worse, but since this is such a clear and simple to understand abuse of power, it'll probably hurt Trump politically. At the very least it should make him a little less likely to win in 2020.
Thanks, will be interesting to see how it develops over the coming months.
If he's impeached next year how would that effect the republican candidate for 2020? Do they have one lined up already? I'm assuming they wouldn't have time to go through the usual processes of selecting a candidate
