Does this campaign have a pulse? Fifteen-term Indiana GOP congressman Dan Burton will face a primary challenge from John McGoff, the Marion County coroner.

It’s actually McGoff’s third run at Burton, and he’s done pretty well for an underfunded challenger in his previous bids. The first time, in 2008, he garnered 45 percent in the GOP primary; he won 19 percent in a large field in 2010, when Burton eked by with 30 percent.
