Biden 2024 Re-Election Bid Sets Up Potential Trump Rematch

WASHINGTON—President Biden opened his 2024 re-election campaign by casting Republicans as a danger to democracy and abortion rights, while the GOP countered that the presidential contest would pivot on the faltering economy and Mr. Biden’s age.

Mr. Biden formally launched his bid for a second term Tuesday with a video announcement, a declaration that puts him on the path to a potential rematch with the man he beat in 2020—former President Donald Trump. The 2024 campaign will play out in an era of political polarization, with both parties fighting over a small number of battleground states and the narrow slice of the electorate that isn’t firmly in one camp or the other.

In the video, Mr. Biden frames the election as a question of “whether in the years ahead we have more freedom or less freedom, more rights or fewer. I know what I want the answer to be and I think you do, too. This is not a time to be complacent. That’s why I’m running for re-election.” He cites abortion access, same-sex marriage and voting rights as examples of freedoms under threat.
