Oh die. You are clueless when it comes to principles. It has nothing to do with purity. Abortion is a line many simply cannot cross period and Mitts pro life record not to mention the rest of his flaming liberal record prevented many true conservatives from supporting him, hence the poor turnout.
It was a close race and had a conservative ran and energized the base i.e. conservatives, conservative turnout and 3rd party voters would've been more than enough to win.
Liberalism did this, not conservatism.
Jackass.
