The giant shift to the left of the Democrat Party only made it seem as if Republicans veered to the right. Parallel motion. Powell and Christy both are contemptible and both are likely to switch parties. I suspect Powell will run for POTUS in 2016 asa Democrat unless the Obama junta permanently seizes power if attempts to repeal the 22nd Amendment don't work.
What should Republicans do? Step aside and let Democrats own and brand everything that happens. If they don't the one party media that not only follows and aids and abets the one party line will manage to blame Republicans. They will therefore lose the House in 2014. Only complete Democrat engineered collapse will allow us to rebuild.
