Founded in 1991, the Republican Liberty Caucus works to advance the principles of limited government, free markets and individual liberty within the Republican Party.

Congressman Jeff Flake has announced that he is running for U.S. Senate in Arizona for the seat currently held by retiring Senator Jon Kyl.

Flake said his priorities include balancing the federal budget, securing the border, and working on transportation and water policy issues. On the budget, Flake said everything needs to be on the table, including changes to Social Security.

Without even waiting to see who else might jump into the race for the open seat, the Club for Growth threw its muscle behind Flake, who for years has railed against excessive federal spending and the pet projects backed by his colleagues on both sides of the aisle.

Flake is a fifth generation Arizonan. He is in his fifth term in Congress. He has consistently been rated in the top five in the Republican Liberty Caucus Liberty Index and has tied Congressman Ron Paul for the number of first place finishes in the Liberty Index.

Flake could potentially face Congresswoman Gabrielle Giffords, who is the instant favorite if she is able to make a speedy recovering from the assassination attempt made on her life in January.
