Don't get hung up on Social Conservatism.
The fatal flaw in your plan.
A significant number of the social right are in the TPM, and theyre not going to be happy in the back seat. That goes for the Bible Belt republicans and the Old Bush Base as well why do you think McCain selected Palin in 2008?
The TEA Party is not a problem for the republican party. It's an asset. Only the gullible are swallowing the leftwing propaganda about the TEA Party.
If it comes down to
1 DNC....Obama
2 RNC....Romney, Perry, Gingrich, Polenta, etc...
3 TP......Bachman or Palin
You don't think the 2 & 3 are going to split the same votes?
