No I was NOT a Romney supporter but lord McCain's treatment using whatever means necessary to take him out and most especially with the assistance of the Reverend Huckabee dissolved their credibility factor.
McCain viewed Romney as his biggest threat, as he had the personal fortune to wage a strong campaign. Huckabee viewed him as his biggest obstacle to getting the conservative vote against McCain. That, my friend, is politics.
The thing is, after Fred Thompson got out, to argue that Mitt should get the conservative mantle was laughable, just looking at his record and flip flops.
