Texas politicians have never been strangers to presidential ambition. Sam Houston ran for the White House twice, and in the decades that followed he was joined in the losers’ circle by such figures as Governor Edmund Davis and U.S. Speaker of the House John Nance Garner. The first Texan to make it to the White House, of course, was Lyndon Johnson. (Ike doesn’t count.) Perhaps inspired by his example, such figures as Lloyd Bentsen, John Connally, and two different George Bushes have thrown their hats in the ring. But never before have we seen a presidential cycle like today’s, in which five Texas Republicans are running or expected to run for the most powerful office in the land.
