CNN has released the lineup for its debate Tuesday night in Sin City, and it's good news for two Republicans aspiring to sit in the Oval Office. Chris Christie, who failed to qualify for the main stage at Fox Business' debate last month, will make a return to it amid burgeoning polls. And Rand Paul will get to stay on the main stage, amid slipping polls and some concern that he wouldn't meet CNN's criteria (candidates had poll at either an average 4% in Iowa or New Hampshire, or 3.5% nationally); Paul saved himself with a Fox News poll out of Iowa on Sunday morning. That makes the prime-time lineup: Donald Trump, Ben Carson, Ted Cruz, Marco Rubio, Jeb Bush, Carly Fiorina, Christie, John Kasich, and Paul. Mike Huckabee, Rick Santorum, Lindsey Graham, and George Pataki will take the early debate. (One Iowa poll just gave Cruz some really good news.)
