will jump on board with anything that they feel advances the Republican Party. Since the Republican Party is the more fiscally Conservative of the two major parties, the TP people primarily use the GOP to run in when they run for office. Levin is really the only one of the three who is an ideological Neoconservative, the other two are just party hacks.
Beck on the other hand is a genuine Tea Partier. Unlike the others you mentioned, he actually has some serious understanding of classic liberal government, the Constitution, banking, and economics in general. Just because Levin, Hannity, and Limbaugh promote or speak well of the Tea Party does not mean they're "taking over" the Tea Party. On most economic issues, the Tea Party and those windbags do have common ground, so, it's understandable that they would be complimentary of the TP.
