Chris Christie Nabs RNC Keynote Which means he probably won't be Romney's running mate By Kevin Spak, Newser Staff Posted Jul 18, 2012 12:40 PM CDT 26 comments Comments Chris Christie delivers remarks and answers questions at the Brookings Institution, a non-partisan, public policy think tank, July 9, 2012 in Washington, DC. (Getty Images) (Newser) – Chris Christie likes to talk, and he's about to get perhaps his biggest platform yet to do so. The New Jersey governor is indeed going to be the keynote speaker at next month's Republican National Convention, NBC News reports. The spot is significant for two reasons: First, because it often kickstarts the careers of politicians with ambitions of higher office (see Obama, Barack). Second, because it's usually distinct from the vice presidential nominee's speech—meaning Christie is likely out of the running to be Mitt Romney's running mate.
