The American people don’t want an Obama or McCain. They’re doing just fine without someone yelling root out the corruption.
The party leadership gave us Obama, from the DNC side, and McCain from the GOP side. So, yes, both parties need to do some house-cleaning.
The present state of arousal on the part of the rank and file is no thanks to GOP leadership. The present state of disarray in the Obamist ranks is, again, no thanks to GOP leadership who until the Tea Uprising were quite prepared to "reach across the aisle" and bi-partisan themselves into irrelevancy.
It is thanks in no small part to a very small handful of talk show hosts and an out-of-work governor and the Tea folk themselves throwing a public fit that the GOP has gotten its spine back from the pawn shop and is ready to do battle.
