Is the Tea Party partying too hard for the Republican party?

Certain Tea Party trends and antics have become too outrageous, and are actually now taking away from the Republican party's influence on the American people.  The obvious example of Tea Partying too hard is the Rand Paul supporter stomping on a protesting woman's head.  This is clearly the worst of the Tea Partying, but whose to say the trend won't continue?
