Actually, both Republicans, Governor, Greg Abbott & Senator, Ted Cruz are going to be sure winners this evening in their primary races. Voter turnout in those races just might not be there because these guys have real challengers and they will politically slaughter whomever Democrat they face in November.
Regardless of Mainstream Media input....the Democrat Party will fall far short of doing any real damage to “TEXAS RED” this coming November, 2018.
NYTimes election website has been quicker than many other outlets.
