So far this year, the media has spent more time fretting about Barack Obama's negativity than it has on any of the arguments that were being mounted. Was Obama going too negative? Was it too soon? Oh no what is happening, in politics? And so the Obama campaign was broadly deemed to have "stumbled out of the gates." All of this presented Mitt Romney with a unique opportunity to come into June as the high-minded, positive candidate. Out of the gutter, above the fray, just talkin' economy with the folks, Obama is a nice guy who is in over his head. So we're at a loss to explain why Romney picked this week to cede this advantage, or at the very least risk, it by crawling down into the gutter himself. He closes out the month with a series of stunts that come across as either base or weird or vindictive, and none were absolutely necessary.
