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.
