That trend appears to have continued on Tuesday night. Biden, with 87% of the vote counted, had already garnered over 138,000 votes in Oakland County, Michigan, a suburb of Detroit. Four years ago, Clinton won Oakland County but with only 92,000 votes, a key reason that she lost the state to Sanders.

The same is true in Macomb County, another Detroit suburb. With 71% of the votes counted, Biden is leading Sanders easily and has already won 58,000 votes. Clinton narrowly won the county in the primary with just under 48,000 votes in 2016.

"Biden's success in the suburbs -- appealing to the base and crossover voters -- closely follows what worked in 2018," said Meredith Kelly, a veteran Democratic operative who was a top staffer at the Democratic Congressional Campaign Committee in 2018. "If Joe Biden wins the states where we won the House popular vote in the midterms, then it's game over for Trump."
