Everyone gets that Savage's new provocation, like his scatological "santorum" coinage, uses ridicule to go after a wingnut. Ridicule can indeed be a powerful political weapon: it transcends ideological boundaries, commanding the attention of voters regardless of their political bent. But Savage's idea is more than that: it's also a wicked satire on the mindset of many conservative men.
Righty guys' support for female conservative politicians is heavily based on sexual attraction. Look which female conservatives get lots of attention on Free Republic: politicians like Palin, Bachmann, in the past Katherine Harris; pundits and news personalities like Coulter, Malkin, and Megyn Kelly. (Also note FR's informal "rules," according to which threads having to do with attractive women must include pics; originally the "rule" was created for Ann Coulter.) One can also cite Rush Limbaugh's rationale for supporting Christine O'Donnell, and the overwhelmingly male crowds Palin drew at her 2008 campaign rallies. Conservative guys tend to support the conservative women they fantasize about banging. Virginia Foxx, a solid and vocal right-winger, but no looker by anyone's reckoning, gets next to no attention. Pretty obvious why.
What a bunch of sexist dickheads. Their standards for conservative female politicians are about the same as their standards for a hookup when it's closing time at the bar. Savage gets to that, and I applaud him.
