Former Rep. Quico Canseco (R-Texas) has been forced into a runoff in his primary, a result that could boost Rep. Pete Gallego's (D-Texas) reelection chances.
The freshman Gallego holds the only swing district in Texas, a heavily Hispanic one rooted in San Antonio. Mitt Romney won it by three percentage points in 2012, while Gallego defeated Canseco by 5 percentage points.
Republicans have been hopeful about their chances against Gallego in an off-year election where Hispanic turnout drops, making him more vulnerable.
But Hurd and Canseco will struggle to catch up in fundraising. Both had less than $200,000 left in the bank as of mid-February and will have to keep spending ahead of the runoff race. Gallego had more than a half-million dollars in the bank as of last month.
Some Republican strategists also believe they need a Hispanic candidate to compete in the district, making the former one-term lawmaker's showing more disappointing.
