Mokumentary: Casey and Obama separated at birth?

Leave it to John Brabender to bring a little touch of This is Spinal Tap to Pennsylvania's Senate race.

The conservative adman, known for his quirky approach, produced a faux documentary called Separated at Birth that questions the "bizarre similarities" between Sen. Bob Casey (D.,Pa.) and President Obama. Released Monday, the 6 minute 49 second Web video features pictures of the two men in identical clothing - including some truly ridiculous sweater sets - and uses a series of interviews with expert "scientists" to portray Casey as a hopelessly adoring copycat.

Arthur Herbenstein, a professor of behavioral science, notes the "type of phenomenon you typically find only in identitical twins."

Asks the requisite portentous narrator, "Is it possible Casey has some Unconscious desire to become one person with Obama?" The key factual claim: Casey has voted with Obama's position 98 percent of the time.

In a neat bit of video-vault jujitsu, Casey is shown from a Meet the Press debate in 2006 when he attacked then-Sen. Rick Santorum (R), whom he ultimately defeated in a landslide, for voting nearly all the time with President George W. Bush. "When you have two politicians in Washington that agree 98 percent of the time, one of them is really not necessary."

Welch, a wealthy southeast Pennsylvania venture capitalist, began campaigns for Congress in two separate districts last year, but withdrew in favor of (now) Rep. Pat Meehan and Rep. Jim Gerlach. Tom Smith of Armstrong County, a Tea Party activist and former owner of a coal mining company and Tim Critz, founder of a medical suppliy company and an unsuccessful 2010 candidate for Congress in the Johnstown-based 12th District, round out the rich-guys-who-can-hopefully-self-fund tier of the GOP race to take on Casey.

"Congrats to some consultant who made a pretty penny on a Web video no one will see," Matt Canter, spokesman for the Democratic Senatorial Campaign Committee, told Politico. “Can’t wait to watch the next episode about Welch, the guy who actually voted for Obama and now pretends he is a tea partier."
