What they're trying to prevent is what happened in Michigan when Tea Partiers, Conservative republicans and libertarians came together and threw a top GOPe RINO out of power.
We Won!
Conservatives working in unison at the State Republican Convention sent a message to the establishment loud and clear: "It's our turn!"...No more `business as usual' politics orchestrated to appease the political masses with hollow claims of conservatism and principles each election cycle, only to disappear into the maze of lobbyists and special interests in the interim...This time, the false claims of an election year cycle fell on deaf ears, conservatism ruled the day...Libertarians, Tea Partiers, and true Republican conservatives unified in one of the most sweeping upsets of the incumbent power brokers I have seen in my lifetime...they have sent both the State and National GOP a clear ultimatum...This time we will not be silent, nor ignored, nor brushed aside...
Keep on Mind that Saul Anuzis was one the rules committee in Michigan that changed the rules the night after the primary to save Romney the indignity of a tie.
