God, this would probably harden Trump's support even more. He would spin it as the liberal machine trying to take him down and impede the "progress" him/his supporters are making.
That in itself might actually start riots.
Seriously?!? The Sheriff of Fayetteville, NC is the "Liberal Machine". The city that hasn't voted for anyone but Republicans since the 1976 Presidential Elections?
Dude the 'liberal machine' part was a joke. It's similar to how conservatives constantly blame the "liberal media" despite Republicans having a massively aggressive propaganda appartus called Fox News and talk radio.
Point is, it doesn't matter who did it or what ideology they are even, because Trump lies so, sooo much and his supporters eat it up so willingly, that he can spin it that way with ease.
