• Speaker Gingrich had a good week. It was not a great week for me. We spent a lot of time talking about tax returns and the changing result in Iowa.
• Mitt Romney • Discussing his loss in South Carolina and revealing that he would finally release his tax forms after much goading. His dad, George, famously released his own tax returns when he ran for president in 1968. “I’m not going back to my dad’s year,” Mitt said, but he would (on Tuesday) release his 2010 return and an estimate of his 2011 taxes. We will not be happy until he tells us where his money pit is. source

• Aren’t jokes supposed to be funny? Mitt Romney’s son Matt was on the campaign trail for his dad the other day when he made an Obama birth certificate joke, in reference to Mitt’s own tax return issues. The joke, and we quote: “I heard someone suggest the other day that as soon as President Obama releases his grades and birth certificate …then maybe he’ll do it.” This was so toxic that Matt joined Twitter just to apologize for the joke:

I repeated a dumb joke. My bad. RT @emilyrs Romney’s son Matt made an Obama birth certificate joke on the trail in NH
