Today Republicans in Missouri will choose their nominee to face Democratic Sen. Claire McCaskill.

The tight, three-way race features six-term U.S. Rep. Todd Akin, former State Treasurer Sarah Steelman and businessman John Brunner.

Rep. Akin joined us to discuss the impact of his time in Congress, as he points to his record as evidence he is a true conservative while his opponents claim 12 years in Washington makes Akin part of the problem. Akin explained why he believes he will win the primary and why he decided not to engage in any negative campaigning.

He also describes the fight for the conservative voters, as several tea-party groups have endorsed Akin while Sarah Palin and others are backing Steelman.
