The conservtives are the independents these days!
I guarantee you that if Romney wins the nomination, then I’ll be voting for some 3rd party conservative. I’ll not leave the presidential slot open. I will write in if that is the only course left to me.
I do believe, though, that a conservative 3rd party that kept the conservative vote would defeat a liberal and a rino who would be splitting the lib and moderate vote with both of them claiming to be running a “centrist” campaign.
