From WSJ:
In the two weeks leading up to Super Tuesday, outside political action committees supporting the Republican presidential hopefuls spent three times as much as the candidates themselves, according to a Wall Street Journal analysis, the latest sign of how these new “super PACs” are transforming electioneering.

Mitt Romney, Rick Santorum and Newt Gingrich spent a combined $2.4 million on television ads during the last two weeks in Ohio, Oklahoma, Georgia and Tennessee, the contests with the most delegates Tuesday, according to a review of spending on TV commercials.
