@Region Philbis,
I'll work on growing up, Region.
Today, a group of Tea Party activists marched over to the offices of the National Republican Senatorial Committee. They are demanding that the latter not financially or otherwise support the campaigns of incumbent Republican senators where there is a primary challenge (i.e. from a Tea Party candidate).
Specifically, the Tea Party movement has focused on veterans Orrin Hatch (Utah), Richard Lugar (Indiana) and Olympia Snowe (Maine).
I was, and probably still am, convinced that the GOP will not break up, but I am less confident about that then I was.
