Mark Martin’s car?
No, this was a photo proposal the Obama campaign did in 08. When they got a lot of negative reaction, the plan to sponsor a car for several fall races was dropped.
That was actually a joke. I remember a number of years back that Mark Martin came out in support of Al Gore in his run for the Presidency. He declared that he was one of the few democrat nascar racers. I assume he’s probably for Obama and would love to drive that car.
