Texas:
Austin/San Antonio/South: Biden 50-38 (+12)
Dallas-Fort Worth: Biden 47-34 (+13)
Houston: Biden 51-36 (+15)
Minor: Trump 58-34 (+24)
Rural: Trump 71-25 (+46)
So the only reason Trump leads in Texas is because there are many more undecideds in the big Metros.
Did Clinton win those metros by a lot in 2016? If they were close, it could be alienated suburban Republicans that will eventually 'come home' to Trump, though it seems unlikely.
The 4 county metro in Dallas was tied but if you add a few more counties it was like Trump +5
