Quayle's Hunt Over

In little-noted primary news today:  Dan Quayle's son Ben lost the GOP primary to another congressman in a costly race out in Arizona.   Ron Barber, who earlier won the election for Gabby Giffords seat, beat back a Dem challenge from the left.  And Richard Carmona won primary for U.S. Senate, and is given best chance for a Dem in that state since 1995.   On the GOP side, a man endorsed by Sarah Palin beat another fellow famous for advocating that students carry guns on campuses.
