The 7 p.m. event is the only planned debate between Republican Ted Cruz and Democrat Colin Allred with the election three weeks away.

On a sunny October afternoon, Republican Sen. Ted Cruz posed for photos with supporters next to his campaign bus in downtown Waxahachie – a historic square complete with quaint shops and a storied, almost mythical-looking courthouse.

Ted Cruz faces off against U.S. Rep. Colin Allred Tuesday night in the first and only debate of the tightly contested race. The stakes are high as the Texas race could help decide control of the narrowly divided Senate.
