He can challenge his access to the ballot prior to the election. He could do it in state courts on a state by state basis if necessary. It only takes one win to cause a major media problem. The public won't understand how Obama could be excluded in one state and will want an explanation, then obama's "got some splannin' to do." I doubt he could survive it. We may get to see Pelosi and Reid in Jail, where it seems most Democrat politicians (and a lot of their constituents) belong.
I believe that's what Orly Taitz tried in New Hampshire. She was unsuccessful. I don't think Dummert would have any more luck.
