Friday was FEC filing day - that day when political campaigns and independent expenditure committees (more commonly known as Super PACs) are required to submit their financial reports for the previous month. Today's reports - which covered the month of March - showed that Romney and Obama had good months for fundraising, while Santorum, Gingrich and Paul had less than stellar months. For Santorum, his debt had begun to pile up by the end of March, and looking over the numbers, the logic behind his decision to drop out of the race in mid-April is reinforced.

On the Super PAC end, the group supporting Romney - Restore Our Future - continued to pull in big donations, while Priorities USA, the group supporting Obama, continues to see slightly anemic numbers. Gingrich's Super PAC continues to be financed almost exclusively by the family of Sheldon Adelson, the Las Vegas casino magnate, and Karl Rove's Crossroads is king where fundraising is concerned.
