“For example, Chris Matthews asserting that conservatives were giving Romney a long leash (ideologically speaking) because they are racists, I mean, come on — what kind of political commentary is that? That was essentially a voter suppression campaign, to tar conservatism and shame conservatives out of participating in politics.”

Despite egregious examples like that, Freddoso said most of the anti-Republican bias in the media was not intentional, but rather the product of the “liberal bubble world in which most journalists live — especially in New York and Washington.”

“When you’re a liberal, and 90 percent of your colleagues are liberals, and the only exposure you have to conservative thought is perhaps a few cranky Internet commenters or people who dog you on Twitter, it skews your perception of political opinions — of what’s mainstream and of what real people think about,” he said.
