So what exactly is the deal with Sen. Jim Bunning (R-KY) and the potential new GOP candidate, Kentucky Sec. of State Trey Grayson? Is Bunning going to hang up his cleats -- or is he still in it to win it in 2010?

Yesterday, Grayson formed an exploratory committee for a potential bid -- but said he'll only actually run if Bunning retires. Keep in mind that it's widely reported that the GOP leadership wants Bunning to retire, rather than protect him as a weak incumbent in what should be a decent red state for them, and Bunning himself has accused them of sabotaging him.

Here's where it gets tricky. It was reported that Bunning gave Grayson permission to do this -- seemingly a giveaway that he'll retire and anoint Grayson as his preferred successor, thus giving the GOP a much more electable candidate. The problem is, Bunning's spokesman is publicly indicating otherwise: "Senator Bunning has every intention of running."

Bunning's spokesman would not comment to the Courier-Journal on whether Bunning had met with Grayson. A call I have placed to him on this same question has not been returned.

I asked a Grayson spokesman for confirmation on whether Bunning gave such permission, and he would not comment further beyond Grayson's original statement: "I have formed an exploratory committee to allow me to formally raise and spend funds as I seek support for a bid for U.S. Senate. I have no plans to run against Senator Bunning. This exploratory committee will allow me to travel the Commonwealth, meet with potential supporters and lay the foundation for a campaign."
