Castro should try for Governor of Texas in 2018 or try to unseat Cruz.
He'd lose both races in a landslide, especially the gubernatorial race. I could see Abbott winning 45% of Hispanic males, even against Castro.
OOC, how well did Abbott do among Hispanics in the 2014 race?
CNN's Exit poll shows him winning Hispanic men by 1 (49-48) and losing Hispanic women by 21 (39-61), so a total loss of 11 points (44-55), which is still not bad at all. Cornyn apparently won Hispanics by 1 (49-48), although that's probably a bit too GOP-friendly. Still not a bad showing for the GOP. Abbott now seems to relatively popular among Hispanics, he had commanding leads in a poll that showed Trump only leading by 6 in Texas.
