PPP's new Texas poll finds a relatively tight race, at least on the curve of recent Presidential election results in the state. Donald Trump leads with 44% to 38% for Hillary Clinton, 6% for Gary Johnson, 2% for Jill Stein, and less than half a percent (0) for Evan McMullin. In a head to head contest Trump leads Clinton 50-44 in the state, which Mitt Romney won by 16 points in 2012.
A Democratic victory in Texas this year remains a stretch but within the numbers there are signs of Democrats being positioned to become seriously competitive there in the years ahead. Trump's lead is based entirely on his holding a 63-33 advantage among seniors. With voters under 65, Clinton leads him 49-45. And when you look just specifically at voters under 45, Clinton leads Trump 60-35. Older voters are overwhelmingly responsible for the Republican advantage in Texas, and generational change is likely to help Democrats become more competitive.
A big piece of that generational change is the increasing racial diversity of the electorate in Texas. Trump has a 69/25 lead with white voters but the reason the state's so competitive overall is that among non-white voters Clinton has a 73-21 lead, including a 68-27 edge with the state's booming Hispanic population.
