They will not support him in the primaries. They likely will support him in the general if he wins the nomination.
I think you’re wrong about conservatives voting for lib republicans like Romney because “where else are they going to go.”
The same people made that argument when RINO Crist was running for governor in Florida. There was no way I would ever vote for that swish tail lib Crist even if he were the only one running. I didn’t vote for him then, I won’t vote for him now that he’s running for senate.
People jumped on my case then about supporting republicans, but now those same people know Crist and agree with me. They’ll never vote for Crist again. It just takes some a little longer to realize what’s happening, but I don’t believe conservatives are going to sell their souls anymore. I don’t care who Romney is running against. If he is the republican candidate, I will not ever vote for him. I’ll make sure everyone I know understands why I can never vote for him. I’ll sit on my hands, vote for every other office and leave presidential selection blank or if there is a good third party candidate, I’ll vote for him or her.
Then I’ll laugh at every person who dares to tell me that a vote for the third party candidate is a vote for the democrat because I already know that a vote for Romney is a vote for the democrat.
