MANHEIM, Pa. — For a second night in a row, Donald Trump told a vastly white audience of supporters on Saturday that they should go to neighborhoods other than their own on Election Day and "watch." Trump didn't elaborate on what they should watch for, telling his crowd in this rural Pennsylvania town that he didn't want to lose the election "because of you know what I'm talking about." Trump's comments were interpreted by voting-rights advocates and others as a subtle but menacing call for his supporters to intimidate at the polls. "You've got to go out, and you've got to get your friends, and you've got to get everybody you know, and you gotta watch the polling booths, because I hear too many stories about Pennsylvania, certain areas," Trump said during a rambling speech. "I hear too many bad stories, and we can't lose an election because of you know what I'm talking about. So, go and vote and then go check out areas because a lot of bad things happen, and we don't want to lose for that reason. We don't want to lose — but especially, we don't want to lose for that reason. So go over and watch. And watch carefully, because we're going to win the state of Pennsylvania." On Friday night, Trump made a similar comment during a rally in the Detroit suburb of Novi. "You've been reading the same stories as I've been reading, so go to your place and vote, and then go pick some other place, and go sit there with your friends and make sure it's on the up and up," Trump said. "Because you know what? That’s a big, big problem in this country, and nobody wants to talk about it. Nobody has the guts to talk about it. So go and watch these polling places. Make sure it’s on the up and up. Please. That would one hell of a way to lose.”
