DNC Goes for Mitt/Taxes Blood

On Tuesday afternoon press call, DNC's Patrick Gaspard says Romney's "failure to release years' worth of tax returns" makes it unclear whether he "paid sufficient taxes" on all his income over the years.

Gaspard: "Mitt Romney has been ducking and dodging the tax return issue."

USC tax professor Ed Kleinbard says documents revel no information about Bay Stater's IRA account.

Also asserts frontrunner's blind trust could have been making decisions "based upon Gov. Romney's political needs."
