The Club for Growth, a PAC supporting free-market solutions in the economy, took sides in the potential Democratic primary to replace U.S. Sen. Marco Rubio, R-Fla., in 2016, launching a new TV ad on Tuesday.
The new ad praises U.S. Rep. Alan Grayson, D-Fla., for opposing the Export-Import Bank, while hitting Murphy for supporting it. The new TV spot starts on MSNBC on Wednesday. Murphy launched a bid for the Senate back in March while Grayson has left the door open to entering the contest.
