Rush Limbaugh added an interesting footnote to our disagreement with Mark Levin on the Delaware Republican Senate primary contest. We thought that Rep. Mike Castle was the preferable candidate under William Buckley's rule of thumb that conservatives ought to support the rightwardmost viable candidate in a given race. Levin supported Christine O'Donnell as the rightwardmost candidate in the race.
Today, I had the opportunity to put into practice William F. Buckley's much discussed rule which calls upon conservatives to vote for "rightwardmost viable candidate." In the Maryland Republican gubernatorial primary, that candidate was former governor Bob Ehrlich, who is neck-and-neck in the polls with incumbent Democrat Martin O'Malley.
