It truly is insane. Roberts came within 7 points of losing to Wolf last month. He know he needs the support of Wolf's voters in order to win. So who does he bring in to campaign with in order to win those voters back? McCain and Dole and Bush; the very image of what Wolf's supporters detest about the GOP. The GOPe is so completely blind to what a huge segment of the party wants that it isn't funny.
Roberts is losing more of the mushy middle vote than he is the solid conservative vote. McCain, Dole, and Bush are what is needed to convince Kansas Republicans (a distinctly different bunch than those nationwide) to vote for Roberts instead of Orman. They love the idea of an “Independent” who will “fix” what’s wrong with Washington and turn it all into a Land of Oz where Dorothy and Toto can be happy ever after. But, when they find out that he is a Democrat, they won’t vote for him.
