Super Tuesday exposes an age divide, a bad sign for Democrats in the general election

Super Tuesday results have exposed the dramatic divide among age groups in their support for Joe Biden and Sen. Bernie Sanders, which could be a bad sign for Democrats in the general election, no matter who the nominee is.

Simply put: Exit polls have shown that Biden’s surge is being driven by overwhelming support among older voters, while Sanders has dominated among younger voters.

As an example, in Virginia, which provided Biden his first big win of the night, he did progressively better the older voters were, winning 76% of those 65 and older, compared to just 7% for Sanders. Yet despite losing the state, Sanders won 57% of voters aged 17 to 29, compared to just 26% for Biden.

The problem for Democrats is that once one of them becomes the nominee, that person will have to do well among both groups in the general election. Specifically, they’ll need bigger margins among young voters and will have to eat into President Trump’s relative strength among older voters.

To be sure, it’s true that primary voting patterns don’t always translate to the general election. For instance, nobody would expect Trump to beat Biden among younger voters, even if Biden has struggled with younger voters in the primaries. However, when results are so lopsided, they can help provide an early measure of enthusiasm that could carry over to November.

For instance, Barack Obama dominated among young voters in the 2008 primaries, and those voters became a core part of his winning coalition. Specifically, he won young voters by 34 points in 2008 and 23 points in his 2012 reelection bid. But Hillary Clinton, who struggled with younger voters in the 2016 primaries, carried younger voters by a smaller 19-point margin against Trump. While that may not seem like a big difference, given that the race came down to a few key states decided by razor-thin margins, it could make a big difference.

Biden’s weakness among younger voters should worry Democrats as they begin to coalesce around him as a nominee. As a socialist, Sanders tends to do worse among older voters, who are generally more moderate — even within the Democratic primary. His big promise is that he’ll be able to win in November by bringing in a lot of new voters. But that strategy has not borne out during the nomination fight. So if he can’t compete among older voters and can’t significantly boost turnout among other voters, he’d struggle to beat Trump.
