After Trump's yuge rally in Orange County, CA, protesters outside the venue started trashing a police car, and acting badly enough that 20 arrests were made. Similar to the protests and quasi riots outside of the canceled rally in Chicago.
These crowds carry signs saying "Bernie," they chant "Bernie," and are all Millennial age. And yet unlike actual Sanders supporters, hardly any of them are white, and their slurs are about people being racist and sexist, when the Bernie bros don't care about identity politics whatsoever, but rather populist economic matters (minimum wage, student loans, free health care, etc.). Identity politics and culture war stuff is Crooked Hillary's schtick.
If the black agitators in Chicago or the Mexican agitators in California were truly fans of Bernie, then he would be cleaning up in states with large non-white populations. It stands to reason that these agitators are, if anything, supporters of Crooked Hillary.
Mostly, though, they're just paid protesters, as Roger Stone has said, and as Trump has begun to make clear as well. They're part of MoveOn.org, Black Lives Matter, and other groups funded by George Soros, mediated by David Brock, and in general working on behalf of Crooked Hillary and the globalists.
Another of their goals is to sow discord between the Trump and Sanders voters, who overlap on populist economic policies and non-globalist foreign policy (albeit with Bernie being less nationalist, and merely non-globalist). We shouldn't fall for that, since we'll be courting them in the fall, especially in certain states that we need to change from blue to red, like Michigan (which Bernie won, and not because the whole state is blue-haired SJWs with $100K in student loan debt).
Instead, online or in real life, whenever they show these paid protesters with Sanders signs, we should ask the others in the audience, "Oh please, if they're Bernie bros, then where are all the white people at?" It not only unmasks the protests as false flag operations from Crooked Hillary, it also reminds the Sanders voters how their primary season would be going if there weren't so much diversity in America.
