What would Texas map look like when it flips(2016 or 2020)?

according to the exit polls...

Just as a reminder, in 2008, McCain got 35% of Hispanics in Texas and they were 20% of voters (Cornyn actually got 36%).  It was closer to 38% for Perry in 2010, who got similar numbers to McCain overall, and undoubtedly higher down the ballot, as those politicians got better numbers. 

There were very little gaps between whites in age, sex or whatever (we're talking 69-30 McCain 18-29 yr olds v. 78-20 McCain 65+olds)

Sure, Hispanic voting turnout in Texas is laughable, but if they keep voting at the 35% level (in theory), they would probably need to get up to 35% (or 35% in combination with Asians) of the total voters to flip the state, at minimum.

So, what would we be looking at - 15-20 years at earliest?  Of course, the Democratic party both locally and nationally, has been ignoring Texas Hispanics, making the same silly assumptions I see above.  And in the past 15 years, we've gone from Republicans regularly getting 20%-25% of the Hispanic vote in Texas, to getting 35%-40% regularly.

But really, does nobody want to project what a democratic win will look like in Texas under short term political climate?

It is rather difficult to make that type of projection for the simple reason that Democrats haven't won a statewide race since 1994 and haven't gotten over 46% in any statewide race since 1998.
