A Pennsylvania Republican running to unseat Democratic Sen. Bob Casey has released a video examining Obama's birth, but not the usual skepticism about where he was born.

In an over 5-minute-long "mockumentary" posted by Republican Steve Welch's YoutTube channel, actors pretending to be doctors and journalists run a phony "60 Minutes" like investigation into "eerie similarities"  between Casey and OBama, alluding in the title that they may have been "Separated at Birth:"

The video is built off of the point frequently referenced by the Welch campaign, that "Casey has voted with Obama 98 percent of the time." In addition to a near perfect record of support for Obama's policies, Casey appears in pictures dressed nearly identical to Obama throughout the video.

Do you think the video was funny or weird? Do you think spoof ads are effective or even appropriate during the country's current political and economic situation?
