I believe it's simply over money, the left and Rino's have melted into one DC group they control trillions of dollars and to keep corruption going aka money flow they cannot allow a third group in the mix, the Tea Party is a threat to their money flow, Carl Rove and the far left see eye to eye on this and it will be a difficult battle to change things but if enough people decide they have had enough ignore the media and vote for those who will kick out the old guard we can win.
