I get this a lot on here for being the only true swing voter around. I guess not pushing either one of the parties or neither is confusing to everyone. Yes, I am pro-Romney and 100% serious about it. Just don't rub it in my face too much when he loses.
There is nothing secret about it. Target a 25% top rate and adjust that downward if reality is that it won't balance the budget. It's an excellent way for Romney to raise taxes on the rich while looking like he's cutting them, but also selling the growth model to offset any potential increases in real rates. The exact itemized deduction cap is the beauty of Romney's humility--he doesn't claim to know the exact figure and is willing to let congress wrangle out a number. So what if it's $17,000 or $25,000? The left is making a mountain out of a mole hill there.
While you say there's nothing secret about it, that's not what he's actually campaigning on. While you're likely presenting the best possible version of his arguments, IMO Mitt has continually demonstrated that he will listen to whomever is yelling at him the loudest. In the primaries that was the Tea Party and he said some really crazy things. Here, those votes are in the bag and he's going off the other direction saying he's not actually supporting a massive tax revenue cut and that he plans on forcing insurance companies to cover pre-existing conditions. I also know that he signed the Grover Norquist pledge so he's, right off the top, totally not committed to the bipartisan solutions he keeps claiming he'd achieve.
I honestly have no idea what he would actually do, but I do know there's a reason he didn't even bother running for a second term in Massachussetts.
