As if Jennifer Rubin and the WaPo know anything or care about the conservative movement. What a bunch of rubbish in that article.
Gingrich's "ethics violations" may be bogus but he did have to give up being Speaker at the time of Clinton's impeachment because his own past affair came to light. He has plenty of vulnerabilities for the media to attack.
There is no perfect conservative candidate running. The 3 conservatives that have some chance of getting the nomination are Gingrich, Perry, and Cain, but whether any of them would be able to beat Obama is uncertain. If Romney gets the nomination, the election will be another "lesser of two evils" choice, but most elections are. We can't afford another 4 years of Obama.
I rarely vote for a candidate. Usually I'm voting against his opponent.
