It is a sign of how poorly Donald J. Trump is doing in the polls that he already is working on his reasons to be a sore loser.
The system, he says, is "rigged" against him and his voters.
"I'm afraid the election's going to be rigged, I've got to be honest," he warned in a rally in Columbus, Ohio last Monday, a sentiment he echoed later that day on Sean Hannity's Fox News program.
"I'm telling you, November 8, we'd better be careful, because that election is going to be rigged," he told Hannity.
Trump's only evidence for fraud consisted of "precincts where there were practically nobody voting for the Republican" in the 2012 election. "If you don't have voter ID," he said, "you can just keep voting and voting and voting."
