The same thing was said in 2016 and that didn’t happen. Case in point, media and don sayers were talking about how Texas could be flipped. Y didn’t in 2016 and it didn’t in 2018; hell he gubernatorial election saw the GOP candidate handily beat the democrat who was a Hispanic. Also, individuals bemoaning demographics fail to account that the GOP is becoming the Caucasian party, it is. They also assume that the democratic muli-cult alliance in the party will hold, it will not. We are already seeing the beginnings of the collapse into smaller party groups. In this environment the party with the latest demographic group of the plurality will end up calling he shots (for however long he republic has left)  This is why the left, and old guard GOP are afraid of Trump. Trump himself is just a combat boomer hit his rise signals the rise of Caucasian identity politics.
