FILE - In this June 25, 2012 file photo, Wisconsin Gov. Scott Walker speaks in Chicago. Louisiana Gov. Bobby Jindal and New Jersey Gov. Chris Christie have been tapped to lead the Republican Governors Association. Both are Republican rising stars considered likely White House contenders in 2016 if Mitt Romney loses in November. Jindal will chair the group next year, with Wisconsin Gov. Scott Walker as vice-chair. Christie is set to take over in 2014 _ a clear sign he may seek re-election in 2013. Christie has said he’s still mulling that decision. (AP Photo/Charles Rex Arbogast, File)
