If folks are wondering about Santorum and DeMint supporting Romney in the past, what is going on now since the 2010 election the R party is kind of like when the officer corps starts figuring out the war is lost, but the politicians don’t want to give it up.
The R establishment has listened to Tea Parties, and knows people want political outsiders, and so forth, but to career politicians it’s all just background noise drowned out by them salivating over the next election. In their typical pavlovian response of preparing for it in the same way the always have they simply worry about getting big bucks in their campaign chest. So even though they listened, I don’t think they really get it. Private citizens get it, but politicians are only little by little understanding just how sick of them people are. It just takes elections to prove it to them.
DeMint even says he had a change of heart AFTER he was elected. I think they both realize that things have drastically changed from when they first were elected.
They will all listen when they see who we vote for in the primaries. And with the Tea Party, voters will vote more intelligently, as they did in the last election.
