“What’s important, if you are running for president, is that the American people know who you are and what you’ve done, and that you’re an open book,” said Obama in an interview with local New Hampshire television station WMUR. “And that’s been true of every presidential candidate dating all the way back to Mitt Romney’s father.”
This could become a serious problem for Romney's campaign. The fact that he's not releasing his tax returns suggests to just about everybody that he has something serious to hide. His campaign bowed to pressure and released one measly year's worth of tax returns back in January, along with their estimates for another year. Will they bow to pressure again? It's possible, although Romney surrogates are now saying that the American public should be happy with the one year's worth of returns they've got, and that whiners who want to see more should "get over it."
