Specifically, I’m wondering about an odd phenomenon that I’ve noticed: the number of Donald Trump and Bernie Sanders supporters, and to a lesser extent, the supporters of Ted Cruz and Hillary Clinton, who seem to genuinely believe that there is a silent majority of folks out there who agree with them. Over and over I have asked these folks what they think will happen in the general election, given their candidate’s significant handicaps: Trump’s vulgarity and sky-high unfavorables, Sanders’s huge-government agenda, Clinton’s scandals and well-at-least-they’re-better-than-Trump favorability ratings, Cruz’s unappealing style and reputation as the hardest of ideological hardliners.
Sums it up. Dunno about lefties, but within the right wing there's a serious case of delusional thinking that we are the "silent majority" and someone like Trump (or even Cruz) is palatable to the rest of the country who aren't partisan fruitcakes. Right wingers are largely a bunch of over the hill angry talk radio listeners who think the rest of the country agrees with them. When Rush Limbaugh says the polls are skewed and Romney will win in a landslide the dupes eagerly lap it up like little puppies, uncritically.
