Congressional candidate Mark Oxner (Republican) has released one of those. It was released last night.
It's titled "Turn This Ship Around: Mark Oxner For Congress" (watch below). Oxner, 40, is running in Florida's new 27th Congressional District against uber-liberal, former Congressman Alan Grayson (Democrat).
The video not only slams Grayson, but also Barack Obama. It depicts Obama as the demented captain of ship about to sail over a deadly waterfall. Grayson is accurately portrayed as Obama's faithful parrot.
Grayson is known for his outrageous and often deliberately false statements. In 2009 Grayson said that Republicans "want you to die quickly" (see video, left).
