Zeke Miller had this chart up on BuzzFeed last night outlining television spending by super PACs supporting the four remaining Republican candidates for president. Romney's spending advantage is no secret, but at a glance like this, it is pretty jarring.

Miller notes that the chart only includes television spending supporting the candidates, not spending on online and direct mail campaigns in which the pro-Ron Paul super PAC has spent over $3 million this cycle.

Mitt Romney's campaign raised $11.5 million in February, the second-best fund-raising effort in his entire 2012 quest for the White House.
