Paul plans weekend offensive in Ky. Senate race

Kentucky Senate candidate Rand Paul (R) is using the second last weekend before the May 18 primary to hit GOP rival Trey Grayson with a new TV ad.

The 30-second spot, which goes up statewide Saturday on broadcast and cable, says the secretary of state will support "big government" if elected to the Senate. The ad was produced by the Strategy Group for Media, an Ohio-based firm.

Meanwhile, Rand is getting hit by a TV ad launched by the American Future Fund, an Iowa-based 501(c)(4) group. The ad says Paul isn't standing up for "real Kentucky values."

Paul has been leading in most recent polls but Grayson was recently endorsed by Senate Minority Leader Mitch McConnell (Ky.), who made a rare foray into a contested primary.

Watch both ads after the jump.
