There are idolators on FR who tear down every other candidate except their own. You should stop listening to them. There were plenty of adequately conservative candidates like Perry, Gingrich, Cain, etc. Each had various problems, but the key is that people who harped on those problems were doing that because they wanted a different candidate to the point of irrationality. Those people can simply be ignored. Argue for a conservative candidate and why he or she is conservative and leave it at that.
Do you have a strategy to get to fifty one Republicans in the US Senate?
