New numbers in the Kentucky Senate race find the Republican primary widening while the Democratic primary is in a dead heat.
Rand Paul, the ophthalmologist son of Rep. Ron Paul (R-Texas), is leading by 16 points in the Republican primary.
A WHAS11/Courier-Journal Bluegrass poll found Paul had 49 percent of the vote while his opponent, Kentucky Secretary of State Trey Grayson, had 33 percent. And 11 percent remained undecided.
Paul has the backing of the Tea Party movement while Grayson is backed by the Republican establishment, including Senate Minority Leader Mitch McConnell (R-Ky.)
On the Democratic side of the race, Daniel Mongiardo and Jack Conway are in a virtual dead heat, with Lt. Gov. Mongiardo leading by one point.
The WHAS11/Courier-Journal Bluegrass poll found Mongirado had 38 percent to Attorney General Conway's 37 percent.
Two months ago, Mongirado led by 18 points but Conway had made up the ground. And with the primary rapidly approaching, only 12 percent of the voters are undecided.
Voters go to the polls May 18th. Sen. Jim Bunning (R-Ky.) is retiring.
