Jeb Bush, Rick Perry, Rand Paul, Chris Christie, Ted Cruz, George P. Bush

This combo of 2015 file photos, from top left clockwise, shows former Florida Gov. Jeb Bush, former Texas Gov. Rick Perry, Kentucky Sen. Rand Paul, New Jersey Gov. Chris Christie, Texas Sen. Ted Cruz and Texas Land Commissioner George P. Bush, bottom right. Texas doesn’t open the voting in presidential campaigns like Iowa and New Hampshire do, but the 2016 Republican race already feels well underway in America’s largest conservative state. Texas’ plan to hold its 2016 primary on March 1 means that only the traditional two early voting states, along with South Carolina and Nevada, would predate it. (AP Photo/File)
