Just a thought: It has been oft noted that beginning in 1952, there has been only one Republican national ticket that did not include either a Nixon, a Dole or a Bush. That year happened to be the year when Republicans did the worst they have ever done post WWII. And the nominee was an irascible U.S. senator from Arizona. Conservatives might think it makes sense not to let history repeat itself – especially since in that case, at least, the Arizonan was paving the way for a move of the whole party rightward, whereas in this case the Arizonan is somebody who on many issues aims to pull the party leftward. Not a happy thought….
