Big Surprise: Texas is Safe R. Hillary maxed out the urban areas and still only got 43.2% of the vote. There just aren't enough votes to elect a democrat in Texas.
There is a lot of untapped potential in the suburbs.
What makes you say that? Trump was the worst possible candidate for these voters, and he almost won 60% of them! Let's stop acting like the rural areas are keeping TX red and the metro areas are just overwhelmed by rural voters. Rural voters were EIGHT PERCENT of voters in the Texas exit polls. That is EIGHT OUT OF ONE HUNDRED, lol. Suburban voters made up 48% of the voters, and they voted 58% for Trump. Republicans have Texas BECAUSE they have a solid base in the suburbs, not because the suburbs are a swing region and GOP voters outvote them/get just enough there.
The Texas exit polls match the popular vote pretty well, and some simple math says the GOP coalition was made up as follows:
54% Suburban, 35% Urban, 11% Rural. Republicans would have won Texas without a SINGLE rural vote in 2016. The suburbs are solidly Republican, even as they swung away. Keep dreamin'.
