The Democratic turnout overall has risen, with Iowa, North Carolina and Texas topping 2016 levels, but not the 2008 spike. Virginia was an exception, jumping from 986,000 votes in 2008 to 1.3 million.

Much of that increase is coming in American suburbs that will be pivotal to the November general election.

Consider Burnsville, part of once-reliably Republican Dakota County. The sprawling community has grown more racially diverse and more Democratic in recent years. The strip mall where Hayes grabbed a coffee also housed a halal grocer linked with an African restaurant and a Latin grocer linked with a taco shop.

A surge of anti-Trump sentiment in the area helped Democrats flip a Republican-held House seat in 2018. Now Dakota County is among the places Trump’s campaign must pick up ground if it wants to make good on its promise to win Minnesota in November.

“The suburbs have been a killing zone for Republicans in the Trump era,” said GOP strategist Alex Conant, a top adviser on Florida Sen. Marco Rubio’s failed 2016 presidential campaign. Conant said Republicans must do better to attract young families and professionals or Democratic gains in suburbs will almost certainly continue.
