From Hot Air:

Count up the delegates at the close of business on Tuesday night and whoever’s got the bigger pile is your nominee, says Bill Clinton’s ambassador to the UN turned Secretary of Energy, knowing full well that even if Her Majesty steals Texas and Ohio from Obama the margin won’t be enough to close the gap. Thus did a man once touted as Hillary’s VP, who spent Super Bowl Sunday glued to the tube with Billy Jeff himself, render a de facto endorsement while pretending not to endorse anyone at all. Exit question: If Obama beats her in both states and she refuses to concede by the next day, does Richardson make his endorsement official?
