They seem to forget that there is an election coming up in less than 2 months
If you think his regime will let the election results stand if it doesn't go in his favour, you're delusional.
No one is calling for violence because they think he's "still popular" and has the country by the throat.
They're warning all of the "he's unpopular and we'll vote them all out in November crowd" that you'd be stupid to not be ready to stand up for those results with necessary force. Because there is NO WAY in hell, democrats are winning the midterms as long as Trump has anything to say or do about it.
By all means, wait for November. But you'd be stupid if you don't have your guillotine sharpened and ready to go for the very next morning.
