No, it is not....The Tea Partiers are primarily soft libertarians, whereas "social conservatives" are actually social authoritarians.The GOP isn't broken. The same thing was said in 2008 and then 2010 happened and the GOP retook the House. Then Scott Walker won his recall in a blue state. Why people make such ridiculous statements after an election is beyond me.
GOP won despite its national leaderships opposition to the Tea Party movement. And the TPM is about 80% social conservative.
