Presidential Bits of Tid: March 9, 2007

Sorry it's been a few days.

• Newt Gingrich admits he had an affair while he was pushing the impeachment of Bill Clinton.
  
• New York’s firefighters union stings “9/11 candidate” Rudy Giuliani.
  
• It’s early, but here are some poll numbers from the American Research Group. Both nationally and in Michigan, Hillary has a slight lead over Obama, with Edwards in third. Giuliani leads McCain among Republicans by a small margin, with Romney taking just 7% nationally and, perhaps more telling, only 10% in his father’s home state.
  
• All eyes will be on Chuck Hagel Monday. Prediction: He won’t run for president, but is instead going to announce his retirement from the Senate. His term ends in 2008.
