Presidential candidate Bernie Sanders is gaining legions of new admirers by shamelessly pandering to voters who want to hear the truth, critics of the Vermont senator say. According to those critics, Sanders has cynically targeted so-called truth-based voters to build support for his Presidential bid. People come to Sanderss rallies expecting to hear the truth, and he serves it up to them on a silver platter, the political strategist Harland Dorrinson said. Its a very calculated gimmick. But while Sanderss practice of relentlessly telling the truth might play well in states that are rich in truth-based voters, like the early primary states of Iowa and New Hampshire, critics say that his campaign could stall in states where the truth has historically been less important, like Florida. At some point in this campaign, voters are going to get truth fatigue, Dorrinson said. Right now, the novelty of a politician who doesnt constantly spew lies is grabbing headlines. But after months of Bernie Sanders telling the truth, voters are going to start wondering, Is that all hes got? Dorrinson is just one of many critics who is eagerly waiting for the Sanders phenomenon to come down to Earth. Telling the truth may be working for Bernie Sanders, but it shows a serious lack of respect for the American political system, he said. Watch: Life as a busker in New York City.
