You do realize Texas Hispanics are much more conservative than in many other states right? Perry got 40% of them to vote for him in 2010. Plus just look at how many Texas Republican officeholders are Hispanic. Cruz for instance is likely to to be the next senator from the state. Just because a plurality of the state is likely going to be Hispanic by the next census doesn't mean that it's going to be friendly ground for Democrats.
1. Texas Hispanics are more likely to be Protestant (40-45% of them are) and conservative than any other states, yes but those are still very small portion of the TX Hispanic population. They are actually farily Democratic compared to the GOP leaning Cuban Americans in FL.
2. He only got 40% yes, but Obama and White still got 60-65% of them in 08 and 10 respectively, so they still have a bloc with them in the state, and it's expected to grow not shrink as some of you are thinking.
3. Dewherst is more likely to win and become the next TX Senator than Cruz is.
4. That's too early to tell, but nothing in the near future is suggesting TX will stay red or that the Hispanics in TX will all become red. The Hispanics in TX are of similar stock as the Hispanics in NV and CA, and neither is going to vote differently anytime soon.
