True, but I'll be more favorably impressed if she does it in 2020.
That's not going to happen.
She could have a serious shot, post-Trump. Trying to challenge him will kill any chance of that, and she knows it.
That's exactly why I would be more favorably impressed. It would show that she has some cojones. Metaphorically speaking of course.
Besides which, if she were to challenge unsuccessfully in '20 it doesn't necessarily kill her future, particularly if Rump subsequently crashes and burns even worse than he's already doing. At that point the public conclusion is more like "guess we should have gone with Haley". And considering Rump's track record thus far, crashing and burning is a distinct possibility even before 2020.
So granted it would be a gamble, but it might just pay off.
Trump shouldn't run again in 2020, no point in it...he already did everything he needed to do.
Shoulda, coulda, woulda.
?
What "should" happen is irrelevant.
Trump will run for reelection, whether or not you think he should.
