Romney nomination Tuesday a formality; Arizona GOP primary a battle

The nomination Tuesday of Mitt Romney as the GOP's standard-bearer is a formality.

What's not a given today is the outcome of a brutal, member-vs.-member Republican primary in Arizona between freshman Reps. Ben Quayle and Dave Schweikert.

Schweikert has a double-digit lead over Quayle, the son of former GOP Vice President Dan Quayle, according to the most recent polls.

Both were on the August 2011 congressional trip to Israel in which one member skinny-dipped in the Sea of Galilee.

Quayle did not go swimming but says his family collected water during the side trip to baptize his daughter.

Still, Schweikert, who did not make the Galilee journey, is trying to use the event against his opponent.

Regardless of the outcome, either Schweikert or Quayle will this election cycle become the seventh House lawmaker to lose in a member-vs.-member primary and the 12th member overall to lose.

Among those races are the Ohio Democratic primary in which Rep. Dennis Kucinich lost to Rep. Marcy Kaptur; the Illinois Republican primary in which Rep. Don Manzullo lost to Rep. Adam Kinzinger, the Pennsylvania primary in Rep. Jason Altmire lost to Rep. Mark Critz; the New Jersey Democratic primary in which Rep. Steve Rothman lost to Rep. Bill Pascrell; the Missouri Democratic primary in which Rep. Russ Carnahan lost to Rep. William Lacy Clay and the Florida Republican primary in which Rep. Sandy Adams lost to Rep. John Mica.

In California, Democratic Reps. Laura Richardson and Howard Berman lost their primaries to Reps. Janice Hahn and Brad Sherman. But state law pits the top vote-getters against each other in the fall. So they will go again later this year.

Reps. John Sullivan, R-Okla., Cliff Stearns, R-Fla., Tim Holden, D-Pa., and Jean Schmidt, R-Ohio, lost their primaries to non-members.
