The race to face Chet Edwards could be heading to a runoff, if early returns hold up. Both Rob Curnock and Bill Flores have about 30 percent of the vote in the Waco district's Republican primary. That also appears to be true for the Republican challengers to San Antonio's Ciro Rodriguez. Quico Canseco has 37 percent of the vote so far, but Will Hurd and Robert Lowry both have more than 20 percent. I don't think that's accurate. Flores is on pace for a clear first place finish, but not close to 50%.
