I guess the only plus for McCain on this trip is that there wasn't an oil spill.

Sometimes political attacks materialize all by themselves. John McCain is set to board a helicopter today and travel 150 miles off the Louisiana cost to host a campaign event on the Genesis Project oil rig.

The overarching point is to stress the Senator's newfound commitment to offshore drilling. But the stop also plays into a meme critics have been pushing for weeks. The oil rig on which McCain will be speaking is partially owned by Exxon Mobil. According to the website RIGZONE.com, the energy giant has a 38.38 percent share in the Genesis Project, topped only by Chevron's 56.67 percent.

the DNC sends out an email hitting McCain for his oil rig visit, adding, among other things that "on that rig, it took 10 years from the date oil was discovered until the rig he will be standing on today produced a single drop of oil.

What, 10 years you say?
