The post the other day about the bullshit survey which supposedly showed Obamacare was scaring doctors into early retirement was inspired by finding the Tea Party ties of the group conducting the survey. When someone has an interest in the outcome of something, it's fair to assume that what they are saying can't be taken at face value.
In light of this, it makes sense that Obama's current political focus is on Romney's goals as Bain Capital CEO and his offshore accounts. Romney's campaign is built almost entirely on his success as a businessman leading to his massive personal fortune. In a strategy that must make Karl Rove blush, the Obama campaign is seeking to turn Romney's one strength into an albatross around his neck. They have been hammering Romney's use of his IRA, which were intended to help middle-class workers save for retirement, to shelter tens of millions. They also emphasize his accounts in Switzerland and the Cayman Islands. There is nothing to suggest Romney violated any laws, but he certainly exploited loopholes where possible. Even Republican Senator Lindsey Graham freely admits that Romney gamed the system for his own benefit.
The Republican economic platform is based on the idea that we will all benefit if only we could cut taxes and get out of rich people's way. As the Obama campaign continues to point out, Romney is a guy who (legally) avoided taxes so we'd stay out of his way and is now tasked with saying we shouldn't make rich people pay so much in taxes. Romney is already, as the only other American in the history of the nation to sign an individual health insurance mandate into law, a terrible messenger for the GOP's anti-Obamacare furor. He's a terrible vessel for their economic plan, too.
