The race to succeed GOP Rep. Will Hurd in a Texas district straddling the U.S.-Mexico border is effectively tied, a poll by the Republican candidate Tony Gonzales shows.

Gonzales is not yet the official Republican nominee against the Democratic candidate, Gina Ortiz Jones, in the sprawling district Hurd is retiring from after six years in office. A recount looms over his primary runoff tally against Raul Reyes, whom the initial count showed Gonzales beat by 45 votes out of nearly 25,000 cast the in the race.
