The chaotic events leading up to Mitt Romney's defeat in the 2012 election indicated how far the Republican Party had rocketed rightward away from the center of public opinion.

Moderation and compromise were dirty words in the Republican presidential debates. The GOP, it seemed, had suddenly become a party of ideological purity.
