My guess is that your "We" encompasses a much smaller percentage of "conservatives" than you either pretend or truly believe.
As bizarre as I'm sure it seems to you, Romney has somehow in fact ALWAYS been getting a percent of conservatives supporting him, even when there were real good conservatives available to choose from. As candidates fell by the wayside, more conservatives came to support Romney. Now if Gingrich is getting out, I would not be surprised if most conservatives will be supporting Romney.
You are of course free to support or not support whoever you want. I'm not telling you to support Romney. I'm saying that you do not accurately speak for most conservatives in your claim.
It would be an interesting poll, to find out what percentage of Freepers would say they "do not care" whether Romney or Obama wins.
BTW, for some who would disagree with you, it's because they would actually prefer Obama over Romney.
