Very interesting, especially the parts about voter registration and the electorate:
Hard to see how Democrats win anytime soon with numbers like that considering Texas whites are about 71-74% Republican. Texas is
44.5% non-Hispanic white in 2012 yet the electorate is about 20 points above that mainly because of proportionally lower voter registration rates among minorities. Too bad that online voter registration bill in the state failed earlier this year. Or even further: imagine Texas with same-day registration or automatic voter registration...
The Senate immigration reform passing could have big changes too considering that could potentially expand the Texas electorate by another 1.5m+ voters in the 2020s when the citizenship provision becomes available:
