The difference between Romney and Obama is so little that it really doesn't matter who wins. The political differences between Obama and Romney is like the difference between a Ford and a Mercury - they are only cosmetic.
A Romney victory in the general election would be a huge disaster for conservatives. For the next twenty years or so, the GOP-E will use the Romney victory as proof that the Republican nominee must be a moderate or liberal masquerading as a moderate (like Romney). This will be used as an excuse to forever marginalize the conservative wing of the party. Personally. I feel that a conservative voting for Romney in the general election is a surrender of Reaganism to the GOP-E.

You've nailed it!
