In the next decade or two, the Republican Party is in serious jeopardy of becoming politically irrelevant at the national level. As illustrated by this graphic that G. Elliott Morris posted on Twitter, while college-educated voters of all age levels are more likely to vote for Democratic candidates than non-college-educated voters, there is an even sharper contrast between voting preferences of voters under the age of 45 than voters who are at least 45 years of age:
I’m at the older end of the “18-29 some college” demographic (I attended a community college here in Illinois a number of years ago, but dropped out due to poor grades, failed classes, and a lack of interest in college), so I’m in a heavily-Democratic demographic in that regard.
It might take a decade or two for voters who are currently under 45 years of age to become the dominant voting bloc in this country, but, unless voters currently under 45 years of age become more receptive towards the Republican Party, the Republican Party could become politically irrelevant at the national level. If voters under 45 years of age were the only people in this country who vote, the only states that might elect Republicans on anything resembling a regular basis are Wyoming and West Virginia, and even those states wouldn’t be iron-clad Republican strongholds.
There currently isn’t a reason for younger voters to vote Republican, especially since the modern GOP is a far-right political party centered around Donald Trump’s toxic brand of politics, which is the main reason why the Republican Party is extremely unpopular with younger voters.
