Barton for Senate?

Mark Silk at RNS reports on an effort to draft David Barton to challenge incumbent GOP Senator John Cornyn in Texas. As always, Silk's grasp of the way political and religious themes intertwine these days is spot-on. Really, though, is it possible that an author whose book, The Jefferson Lies, had to be withdrawn because of its own lies, could win a primary? For dog-catcher? For Senate? When you think about the Lone Star State's junior senator, perhaps it is possible.
