Arizona Republican State Senators have this down to an art.

An Arizona state senator involved in an apparent freeway-shoulder scuffle with his girlfriend was not detained because he has immunity from arrest while the legislature is in session, police said.

Officers in Phoenix who were called to investigate a reported altercation found that both Sen. Scott Bundgaard and his girlfriend, Aubry Ballard, had marks suggesting a physical dispute, police spokesman Sgt. Tommy Thompson said.

So, they were both fighting but she goes to jail and he goes home.

Since he’s a Republican, maybe next time he could force her to get pregnant and see a sonogram.  After all, he is a big ole Super DeLux Brand Christian and knows what is right for women.

Bundgaard said the dispute began on the way home from a charity “Dancing with the Stars” fundraiser, after Ballard accused him of “inappropriately touching” his dance partner.

Yeah, he needs to tell that to the folks at Christ’s Church of the Valley, where he’s a neighborhood leader.

And, yes, of course, he was endorsed by Sheriff Joe Arpaio.

Republican men – they’re gonna whack ya one way or the other.
