Currents in the Party

So if the Republican "wave" becomes something of a current, what's the reason? Is it that the Republican Party brand remains one of neoconservatives and President Bush, and the corruption in Congress in the last decade?  There are a lot of folks associated with this era of Republicanism who are ITCHING to get back into power. The Tea Partiers, in theory, will check these interests and be guardians against the imposition of corporate power in the GOP.  Then again, with all the Chamber of Commerce money helping them win,how many Tea Partiers will like and drink establishment Kool Aid after a couple sips?
