Republicans Line Up To Challenge US Sen. Claire McCaskill

Next Tuesday Missouri Republicans will vote for one of three candidates seeking to unseat incumbent Democratic U.S. Senator Claire McCaskill. 

All three espouse conservative ideals, but who will convince enough voters in this close contest to advance to the November election?

In the second half of Wednesday's Up to Date, Steve Kraske talks with two of the candidates: U.S. Representative Todd Akin and former Missouri Treasurer Sarah Steelman. (candidate and businessman John Brunner is unable to join the conversation.)

We'll ask them about Missouri's hot summer and their thoughts on global warming, tax cuts and spending, how the U.S. should respond to Iran's nuclear ambitions, and more.

Learn more about all three candidates from St. Louis Public Radio's Tim Lloyd.
