Thanks as I’m not familair with Kansas politics. It may come down to who’s got the cash for the final advertising blitz.
"Rep. Jerry Moran (R-Kansas) received a big-name endorsement from John McCain today, giving him a boost as he faces a competitive primary against Rep. Todd Tiahrt (R-Kansas)."
I believe that McCain was the early leader on endorsing Moran, we'll see how that turns out.
