Barack Obama’s tax returns have been released. It turns out he hasn’t given a lot to charity (though he’s not as stingy as Al Gore and and doesn’t itemize his underwear) and that the Obamas’ income doesn’t quite mesh with their tales of financial woe.

That said, the main purpose of the release is to put pressure on Hillary Clinton to release her tax returns, which she has promised to do before the Pennsylvania primary. Now, barring some glaring evidence of hypocrisy ( John Edwards’ employment by a hedge fund while he vilified them comes to mind), I doubt this sort of thing changes many voters’ minds. Unless there is some deep, dark reason why the Clintons have delayed and delayed in releasing their returns.
