I like Michael Brendan Dougherty’s list of how to explain a Romney loss to shocked conservatives. Especially this one:

Finally: you didn’t like Romney that much either. So are you really surprised? The entire Republican primary was a search for a “Not-Romney” candidate. In fact, you probably once contemplated voting for Newt Gingrich, Herman Cain, or Rick Santorum precisely because Romney was a flip-flopper who invented Obamacare in Massachusetts. Just a year ago, my dear conservative friend, you were likely very much against the idea of Romney being your nominee. So how can you be surprised that other Americans never warmed to him as a choice for president?

Not only that, but please recall that as unexcited as you were about Romney during the GOP primaries, he really was the most plausible candidate of the lot.
