The Democrats better be careful of what they are wishing for.
This actually could work in favor of conservatives. More specifically, it will work in favor of the THINKING voting public, not just the mindless robots.
Keep in mind the Tea Party movement is not going to go away soon. This reminds me of how the US got into World War II.
Many people don't realize that the US had been ambivalent about entering the world wide fray. (Of course, this deserves a completely different analysis track, as I actually believe much of the CAUSE of WWII was started by American isolationalism, primarily instigated by Roosevelt's New Deal policies, which literally shut down cold trade with Europe and Asia, leading those countries to gear up for war in the early to mid thirties. I digress for now).
When the US entered the war, it was kick ass and take names, and we didn't forget.
The same pattern is arising now. I don't see RINO's doing anything anytime soon. I DO see a lot of dems moving back to the right, though, occupying the current part of the spectrum that the GOP RINO's are occupying, but the current GOP Rinos will simply move to the right, so the entire political spectrum will swing to the right for at least a decade.
