Because no matter how many spin Doctors they get the Republicans will not be able to shake their reputation as the "Party of the Rich" no matter that the Democrats are the party of the "Limousine Liberals."
But the Tea Party has no "party of the rich" stigma attached. The Log Cabin Republicans have no stigma as "the party of the rich."
The more fractured the Conservative end of the spectrum becomes the better off it will be IF they can really agree on Big Tent Politics. I guess as long as the fractured Right can agree on fiscal issues they would be better off than the liberals...
Cause the Democrats are all about the "Big Tent Politics" but couldn't even agree on a bloated budget when they had complete control of the Legislature and Presidency.
