I like Palin, but you are right. Her influence is magnified by the fact that the GOP has neutered itself over the decades. The rank and file are desperate for someone who will stand up and speak up.
They've brought the problem on themselves, though. We've always had Repubs who were outspoken but the rank-and-file too often have taken their cues from the media and find themselves embarrassed election after election into following the warmed-over dishwater served up by the media and the party leadership.
If you want to know where the leaders are coming from in 2012, you have to look at who is leading now. Its a short list. Palin is on it, along with DeMint, and Bachmann, and I like Ryan and Pence. But its a pretty short list.
A few of the wimps are having a hissy fit over this and yet they refuse to do what needs to be done. So, Sarah is going to lead her grizzlies into the viper pit and hope for the best.
