Kelley Paul, wife of Kentucky Senate GOP candidate Rand Paul, has called a news conference later Wednesday to address the attack ad run by her husband's opponent that bashes his involvement in a college group 30 years ago that reportedly mocked Christianity.

While standing by her man, Mrs. Paul, who is a deacon at the family's church, plans to show a new National Republican Senatorial Committee television ad, viewed here, that uses media pundits and numerous NBC and MSNBC anchors (some of whom are more liberal) questioning the ad by Democratic attorney general Jack Conway, with some even denouncing it. The new ad, which says Conway has "Gone Too Far," also makes use of an MSNBC guest appearance by Sen Claire McCaskill, D-Missouri, in which the Obama White House ally calls the ad "dangerous." McCaskill also said in that same appearance that Paul was too "thin-skinned" for walking off stage in a recent debate without shaking Conway's hand.

Conway and Paul are locked in a dead heat for the seat being vacated by retiring GOP Sen. Jim Bunning.

Paul has questioned whether or not he will appear at the next scheduled debate, and officials at the campaign tell Fox no decisions have yet been made.
