The endorsement isn't official, but Kentucky Secretary of State Trey Grayson has received fundraising help from some of the top Republican Senators, including Senate minority leader Mitch McConnell, the senior Senator from Kentucky. Which is why it's surprising that antitax activist Rand Paul managed to outraise Grayson by more than $350,000 last quarter. Both men are running for the seat being vacated by Republican Senator Jim Bunning. Paul benefits from a famous last name: his father Ron Paul is the Libertarian darling of the right. Paul the younger has been attacking Grayson for once voting for Bill Clinton for President and for accepting money from GOP Senators who voted for the stimulus.
