LUGAR CAN’T BE A “SORE LOSER”:  Thanks to a sharp Instapundit reader, I’ve discovered Indiana Senator Richard Lugar cannot, in fact, run as an independent if he loses to Richard Mourdock in the Republican primary.  This is because Indiana has a “sore loser” law that says (Indiana Code Section 3-8-1-5.5) a person who “is defeated in a primary election . . . is not eligible to become a candidate for the same office in the next general or municipal election.”  So no pulling a Murkowski or Christ for Lugar.
