As more data emerge to explain former Vice President Joe Biden’s stunning victory on Super Tuesday, there are two clear demographics that propelled him: African-American voters and suburban voters with college degrees.
It’s a coalition that helped moderate Democrats flip seven governorships, two Senate seats and about 40 House districts (the newly Democratic suburbs alone would have secured a House majority) from red to blue in 2018. African-Americans have long made up a core of the Democratic voting base, but many of Mr. Biden’s college-educated, suburban supporters are right-leaning independents or moderate Republicans who supported candidates like John McCain and Mitt Romney. They don’t want to re-elect Donald Trump. And they’re willing to cross over to vote for a Democrat — a moderate and mainstream Democrat.
These voters might not identify with the “Never Trump” group of conservatives who vociferously oppose the president. But in practice, that’s who they are. They often voted for Republicans in the past and are now firmly anti-Trump. These voters can create winning margins for Democrats in swing states like Michigan, Pennsylvania, Arizona and North Carolina in the general election.
