There were way less Hispanics in the US back then. I would mention Asians too, but they were GOP leaning back then.
If I'm not mistaken, Reagan actually got less of the white vote than a GOP president today would. He got much lower margins in those redneck states like West Virginia and Kentucky than Trump did.
Back then, there was still a significant Union/Blue Dog white democrat vote out there.
Clinton was able to tap into it. Even Obama got some of it in '08.
Republicans had to dial up the Race War shyt in order to keep their hold. Popular vote is over for them but they can definitely win the House/Senate here and there. Presidency is all about the Electoral College because they'd never win it again otherwise.
Only concern for us is Latinos trying too hard to be white and voting like redneck white people.
Best way to avoid that is to make sure Latinos get educated in the 2nd, 3rd etc generation. More educated = less Republican. The newer immigrants eat that Republican shyt up since most have an irrational fear of anything "socialist" and love the message of "family values" and jobs.
It's like Madden '06. Black people got that Tom Brady/Peyton Manning cone of vision where we see everything. La Raza only sees like 1/3 of the field at best and makes decisions based on short term shyt.
