Aha..you are going against the generally held belief here that GOPe is omnipotent and can anoint any candidate they wish.
Me on the other hand believes the voters in primaries are far more powerful than GOPe.
As for Roberts, I am rooting for him over Orman.
My whole point is Roberts is behind in polls because he is too old to travel back and forth from Kansas every week. Orman is exploiting this situation apparently with success. Roberts should have retired at the end of his last term. However that is water under the bridge. He is now the GOP nominee and best luck to him.
