(CNN) – Political novice and Tea Party favorite Rand Paul has an early lead over Secretary of State Trey Grayson in Kentucky’s Republican Senate primary.
With 16 percent of precincts reporting, Paul had 52.8 percent of the vote, and Grayson had 34.2 percent. The last polls in the state closed at 6 p.m. CT.
Grayson is the establishment candidate and was the early favorite. But Paul, a libertarian-leaning physician and son of former GOP presidential candidate Rep. Ron Paul, R-Texas, picked up the backing of some Tea Party groups and had taken the lead in polls leading up to Tuesday’s primary.
On the Democratic side, with 18 percent of precincts reporting, Jack Conway was leading Daniel Mongiardo 46.9 percent to 40.4 percent.
The candidates are fighting to succeed Sen. Jim Bunning, a Republican who isn't seeking re-election.
