It is inescapable that the electorate determines elections. America is changing, and the American People express their increasing diversity and greater academic attainment at the polls. The electorate has become more diverse and more highly educated. Democrats rely heavily on nonwhite voters and have improved with white college-educated voters, while Republicans have cut deeply into Democratic support with non-college whites. — Racial and cultural issues, rather than economic ones, have fueled Republican gains with the non-college white electorate... Over... 40 years, the electorate has become both more racially diverse and more educated. The white share of the electorate has fallen from 84% in 1980 to 66% in 2020. At the same time, the share of the electorate without a college degree has fallen from 84% in 1980 to 63% in 2020. The combined impact of growing racial diversity and rising levels of education is that the share of the electorate made up of whites without a college degree has fallen drastically, from 69% in 1980 to 39% in 2020. In 40 years, non-college whites have gone from an overwhelming majority to a minority of the American electorate. This decline in the non-college white share of the electorate has been very consistent, averaging about 3 percentage points every four years, and shows no signs of abating. At this rate of decline, the proportion of the electorate made up of non-college whites will fall to approximately 30% by 2032... As the proportion of college graduates has grown since 1980, there has been a dramatic realignment in party identification along educational lines. According to the ANES data, during the 3 elections between 1980 and 1988, Democrats enjoyed an average advantage of 14 points in party identification among Americans without a college degree. At the same time, Republicans enjoyed an average advantage of 5 points in party identification among college graduates. By 2016-2020, the Democratic advantage among Americans without a college degree had fallen to only 1 point while the 5-point Republican advantage among college graduates had turned into a 14-point Democratic advantage. https://centerforpolitics.org/crystalball/articles/the-transformation-of-the-american-electorate/
The world, voting landscape, demographics, technology and everything has changed in the last 40 years. No choice but to adapt with it.
These are good statistics. Unfortunately, current GOP wants to only concentrate on the 39% White Without Collage degree. These 39% Americans has no interest in compromising, modernizing their view. They want to live in 1950s America. They are the ones who vote in primary election, and they are the most vocal. They are the one destroying the Republican party. By 2032 when this group became 30% of electorate, GOP will loose any chance winning national election.
