Perhaps it's because you're trying to convince me that 'our' Socialist is somehow better than 'their' Socialist.
Oh, I can agree that Romney isn't nearly as putrid as Obama is in many ways, but in my observation, most of the differences between them are either superficial, or only in matters of degree - not kind.
Both Obama and Romney stand squarely opposed to everything that I believe in. It's no more complicated than that. You tell me that I ought to support Romney, so as to dislodge the monster, Obama. Ok, but from my point of view, there won't be any substantive difference in a Romney administration, so what exactly would compel me support him?
Frankly, folks are just going to have to get used to the idea that Romney hasn't made the sale with a lot of principled conservatives, and that in fact, he's convinced a great many of us that he and Obama are of the same ilk. Browbeating us isn't going to change our minds about him. We've seen the evidence of his cowardly liberalism, and we're repelled by it.
I suggest that you'll find more fertile pastures among the wavering Independents and moderate Democrats, than among the 'line-in-the-sand' conservatives.
