Not bleak but very concerning. Given the racial demographics that will make anglos a minority in the near future, Texas Republicans should be concerned given hispanic and black voting trends.
Per the 2000 US Census: Texas' population: 20,851,820 of which black's constitute 11.5%; hispanic 32% and white 52.4%.
The trend is not good, if traditional voting patterns remain the same. Of course, minority voting strength hasn't been proportionate to population, either.
It's not going to pose a problem this election, but there's little doubt that the GOP must make inroads into the minority voter population in order to survive.
