Who wingnuts will blame when Romney loses.

Ambinder has a pretty decent list here, starting with:

(1) It's the liberal/drive-by/lamestream media's fault. It always is. They covered for President Obama's lapses in Benghazi, failed to hold him to account for his obvious failures, generally failed to vet him properly in 2008, and ignored the scandals during his first term. They tipped the scales. And in the last week, they covered his response to Hurricane Sandy as if he were a conquering hero. They hated Mitt Romney because they were jealous of his success. They ignored Chicago's relentless negative campaign.
