Here's the math problem. Whites will make 67-68% of the electorate in 2020. That means that automatically you're losing political support if you're the Republican Party. W fixed this between 2000 and 2004 by expanding his Latino vote share from 35 to 44% and improving his white margins. Even then so, the Democratic vote remained stable.
The opposing party's vote share usually stays stable. The victorious second term party usually sops up votes that were third party or write in or whatever. So assumptions: the Democrats will remain at 47-48% of the vote minimum. That's their floor.
If Trump loses the popular vote by 1.8% percent, to win re-election, he's going to have to make up that 1.8% PLUS probably 2% more to reach 50%. That means a 4% increase in GOP support. Since whites will make up fewer voters, he's already more votes down in the hole than his 2.5 million votes.
He has two routes. 1 - Double down on his white margins and hope that he reaches 62-63% of white voters 2 - Go for a broad coalition that reaches 35% Latinos and 40+ Asian (the black vote is gone - maximum 10%) and top it off with 60% of the white vote.
This is Trump trying to expand his base but here's the biggest problem. Trump has zero expertise in coalition building. Bannon, even less. The alt-right has no interest in expanding their plurality coalition.
In the long run? "Doom upon all the [Republican] world." They might eke out 2020 but Trump being president really ultimately shipwrecks their coalition. There's only so many whites you can mine before you start running out of votes.
By 2036 - which is 20 years away - whites will make up 57-59% of the vote. It means you'd have to win 75% of whites to reach 45%. Pro tip - the GOP margin among whites has expanded, but since 2004, their OVERALL numbers have barely improved. Bush won 55% of whites in 2000, Trump won 58% in 2016. The white vote isn't simply accelerating towards the GOP at a high enough speed to outweigh the minorities.
The biggest reason that is happening? Economy. Educated whites don't like the Brexit GOP and what they represent. They want good paying jobs that reward them for developing their skills, not working in a factory. They want globalization because it means they can get more clients and more contacts and network around the world (and make more money).
IS ANYONE beginning to understand why electing Trump and the Brexit Right a long term nightmare for the GOP? It has 60% to do with economics, 40% demographics.
You're missing the key parts of how Pussygrabber won this election, and the GOP strategy in general: Disenfranchise whenever possible, and drive the whole process into the mud in order to drive down enthusiasm and thus turnout.
