Lots to digest today.

Mitt Romney won six states on Super Tuesday: OH, AK, MA, VT, VA and ID. Rick Santorum won TN, OK and ND. Newt Gingrich won GA. Ron Paul won no states. Ohio was especially close. It is shaping up to be the most contentious GOP race in decades. Both Romney and Santorum can claim momentum, but the race for the nomination is not over. Now we look ahead to Kansas (March 10), Alabama, Mississippi and Hawaii (March 13), Missouri (March 17), Illinois (March 20) and Louisiana (March 24).
