Roundup: Gingrich's moon-redistricting plan, rude Washington, Ron Paul's bike race Republican presidential candidate Newt Gingrich picked up an endorsement, our colleague Dan Eggen reports, but he might wish he hadn't. It came from a federal prison, where the former House speaker's old pal ex-Rep. Randy "Duke" Cunningham bides his time. Elsewhere, under Gingrich's space plan, moon colonists could eventually form a state, our colleague Joel Achenbach reports. Which, of course, means the state would have congressional representatives, which leads us to wonder what the AP style on that designation would be -- (R-Moon)? Also, our colleague Petula Dvorak tells us what anyone who's been around politics knows: Washington is pretty rude. And our favorite quote from last night's GOP debate came courtesy of Rep. Ron Paul (Tex.). The congressman is getting just a little testy about all these questions about his age (he's 76). I'm willing to challenge any if these gentlemen up here to a 25-mile bike ride any time of the day in the heat of Texas. Consider the gauntlet thrown.
