Trump's base will beat Bernie's in a White House matchup. Here's why.

However, the demographic benefits for Sanders also cut the other way: Younger voters are notoriously reluctant to vote, while white evangelicals and older voters are some of the most consistent voters in the entire population. And the raw numbers aren’t good, either: Millennials and Gen Zers make up just about a third of the electorate vs. older cohorts, with conservatives outweighing liberals by 37 percent to 25 percent.

And when it comes to competing over the voters they share — not to mention those who will cast “lesser-of-two-evils” votes — Trump has several inbuilt advantages that could well put him over the top. After all, in 2016, 12 percent of people who voted for Sanders during the Democratic primaries voted for Trump in the general election, and white working-class voters are more likely to say they will vote for Trump over Sanders than over moderate Democrats. And white voters without college degrees were by far the biggest part of the electorate in 2016.

Trump has the tremendous power of incumbency and a campaign war chest reaching well into the nine figures. And practically from the day of Trump’s inauguration, his re-election team has focused relentlessly on voter turnout efforts that put him far ahead of Democrats online and in other technology efforts, per a New York Times assessment.
