Over the course of the next two months, the Tea Party movement may become to be seen (to mix a few metaphors) as more of a paper tiger than the tail that wags the Republican dog. To put it a little more concretely, the Tea Party may be losing some of its outsized influence over the Republican Party.
This year, several Tea Party challengers seem to be crashing and burning early in the process. This could be very good news for the Establishment Republican wing of the party. Rather than have a candidate implode in the general election, when candidates self-destruct before the primary then they never become the nominee in the first place.
