State Sen. Gilbert Baker (R), who's running for the GOP Senate nomination in Arkansas, launched his first campaign ad on statewide cable television and statewide radio Monday. 

The 30-second spot features Baker saying, "President Obama, forcing America down the wrong track. Congress shares the blame." As he speaks an image of the president dressed in a lab coat appears on screen. The ad also features an image of incumbent Sen. Blanche Lincoln (D-Ark.), but doesn't mention her by name.

"We have to stand up to President Obama and put Arkansas values first," Baker says in closing.
The Little Rock and Baton Rouge-based consulting firm The Political Firm produced the ad.

Lincoln is running for a third term. She faces a primary opponent and there are several Republicans running for the GOP nomination. The primary is May 18.
