Huh? Apparently they used all the ammunition against Romney, so there wasn't any left for Trump. But a closer look and this turns out to be nonsense, the reproaches against Romney were justified:
Quote:In the spirit of spreading culpability for the GOP’s meltdown as thin as possible, The Daily Beast recently served up a new theory that lays blame for Donald Trump at the feet of liberal commentators in general, and New York Times columnist Paul Krugman in particular. The argument is that overheated liberal denunciations of past Republican standard-bearers desensitized conservative and independent voters to the kind of criticism that should’ve been reserved for a uniquely menacing figure like Trump.Conservatives’ Laughable Effort to Blame Liberals for Trump | New Republic
“He was frequently called a ‘bully,’ ‘anti-immigrant,’ ‘racist,’ ‘stupid,’ and ‘unfit’ to be president,” complained Karol Markowicz in a piece that received wide acclaim on the anti-Trump right. “I’m referring, obviously, to the terrifying Mitt Romney.”But when you unearth the context in which liberals used those terms, you find they were being perfectly fair-minded, and the lustrous halo around Romney begins to fade.
Amy Davidson of The New Yorker called Romney a “bully” after The Washington Post reported that as a high school student at the Cranbrook School, Romney had mercilessly bullied a gay teenage classmate.
Ruben Navarrette argued, persuasively, that Romney’s “self-deportation”-based immigration proposals were “anti-immigrant.”
It turns out nobody of any stature in liberal politics called Romney racist, but liberals like Lawrence O’Donnell did quite rightly allege that Romney was pandering to racists by seeking boos from the NAACP national convention, so he could turn around and boast, “if they want more stuff from government, tell them to go vote for the other guy—more free stuff.”
Meanwhile the person who claimed Romney was “unfit to be president” did so in an uncompensated Huffington Post blog post, as did the comedian who, taking cues from CNN’s Erin Burnett, argued it was politically “stupid” for Romney not to release his tax returns.
Krugman frequently questioned Romney’s honesty, but almost always in relation to the fact that Romney used fantasy budget math to mislead voters about his regressive tax reform proposal, or for more discrete lies, like claiming Obama had gone on an “apology tour” after assuming the presidency in 2009.
