Republican voters in two House districts will head to the polls today to select nominees to oppose Democratic Reps. Chet Edwards and Ciro Rodriguez.

In both districts, the March 2 primary elections didn’t produce majority-vote winners.

In Edwards’ Waco-area 17th district, businessmen Bill Flores and Rob Curnock traded attacks in the waning days of the campaign. Curnock, who was Edwards’ 2008 opponent, criticized Flores for saying he voted for Curnock when he actually didn’t vote at all. Flores hit Curnock for accepting a homestead exemption for a property on which he doesn’t reside.

In the first round of balloting, Flores edged Curnock, 33 percent to 29 percent. He is the much better-funded candidate.

In Rodriguez’s San Antonio-based 23rd district, ex-CIA officer Will Hurd and lawyer Francisco “Quico” Canseco are competing for a place in the November general election.

Hurd, who edged Canseco by 34 percent to 32 percent in the primary, has been touting his background in national security policy. Canseco, who lost a 2008 primary, has said Republicans need to nominate a Hispanic candidate in a district that is about two-thirds Hispanic.
