President Obama will continue today in his opening salvo against presumptive Republican nominee Mitt Romney, attacking tax policies that allow investors, including the very rich, like Romney, to pay a 15 percent tax rate on income from their portfolios.

Running for re-election on a slate of proposed tax increases is a tough task, especially given the saggy state of the economy. But Obama has a message he and his campaign believe is toxic to the chances of a Republican nominee who is from the ranks of the super rich. Romney wants voters to think about his success in turning around struggling companies as a CEO. Obama wants them to think about the car elevators that are going into Romney’s beachfront estate in California.
