Four funky GOP primaries

Ambers reviews. The one I'm watching:

KY SEN, Ron Paul's son, Dr. Rand Paul (yes, named after Ayn) is now leading...or slightly leading... in the Republican primary (incumbent Sen. Jim Bunning is retiring). The GOP establishment chose Secretary of State Trey Grayson, but Paul has pushed hard on his party's dissatisfaction with GOP leaders. (There's a bit of Mitch McConnell fatigue in his home state.)  Paul is ostensibly a libertarian, but he's getting support from all the conservative establishment interest groups, including the taxpayers union he once headed.  For TV producers, the Paul pa-son angle is irresistible. And the "audit the Fed" message resonates beyond the confines of the ReLOVEution. Also funky: one of those campaign-aides-posts-something-racist-and-has-to-resign angles. Grayson, again, is running a conventional NRSC campaign against Washington (jobs, Democrats, D.C.); Paul is running against Grayson as an embodiment of Washington. The primary is May 18.
