The 20 counties that will decide the midterms

The battleground counties span the country. In the Southwest, races in several counties will test the GOP’s 2020 gains among Latino voters, a constituency that critics say Democrats have taken for granted.

In the Midwest, suburban counties outside Detroit, Kansas City and Minneapolis moved toward Democrats in 2020, but could be due to swing back amid frustration with the Biden administration over inflation and other issues.

In the Northeast, a pair of counties north of Philadelphia — not far from where Biden spent his early youth — will test the president’s appeal among both working-class and white-collar voters.

In the South, Georgia once again will take center stage as an electoral ground zero, with counties outside Atlanta set to decide major gubernatorial, Senate and House races.
