One week from today, Kentucky Republicans will choose their nominee to replace retiring GOP senator Jim Bunning. The results will tell us a lot about the electorate's dyspeptic mood.
The campaign pits secretary of state Trey Grayson against Rand Paul, an eye doctor and son of Rep. Ron Paul of Texas. Grayson has the blessing of the GOP establishment: Senate minority leader Mitch McConnell, Rep. Harold Rogers, Mitt Romney, and Rudy Giuliani. Paul has the support of passionate outsiders: his father, Sarah Palin, Sen. Jim DeMint of South Carolina.
