Michigan proves Biden could rebuild Dems' "blue wall" against Trump

Two things happened on Tuesday in Michigan. First, Democratic turnout exploded. Second, Biden performed far better with key demographic groups than Clinton did four years ago. If either one of those things happen in November, Trump will have a difficult time winning the state again. If both things happen, the president can kiss Michigan’s 16 electoral votes goodbye—and with them, more than likely, the electoral votes of Wisconsin and Pennsylvania…

Biden’s performance among the wealthier suburbanites in these counties should be highly worrisome to Trump. These voters—particularly whites with college degrees—are accepting of the former vice president in a way they never were of Clinton.

The story of The Trump Realignment has been an exchange between the two parties: More of the well-educated suburbanites fleeing the GOP for the Democratic ranks, with more of the blue-collar rural and exurban voters joining the Republican Party. This tradeoff, while unsustainable for the GOP over future election cycles, never figured to torpedo Trump’s reelection. But what Biden demonstrated on Tuesday was an ability to have it both ways—accelerating the GOP’s exodus in the suburbs while stopping his party’s bleeding in the exurban and rural areas beyond. If he can do that in November, he’ll win.
