Democrats have chosen Chicago to host their 2024 national convention, trying to keep the party’s momentum going after last fall’s midterm election success in the critical Midwest.

The decision, confirmed by a Democratic official who spoke on Tuesday on the condition of anonymity before an official announcement, comes after President Joe Biden personally chose Chicago over finalists that also included Chicago and New York.

Chicago is solidly Democratic, as is Illinois. But holding the party’s presidential nominating gathering in such a pro-union city again demonstrates Biden’s commitment to organized labor - which will be critical to his bid to win a second term in the White House.

The move also could counter Republicans, who last summer decided to hold their 2024 convention in Milwaukee in another critical Midwestern battleground state, Wisconsin.
