The Biden-Harris campaign plans to try to usurp "Project 2025" — the name of a well-funded Heritage Foundation effort to prepare for a second Trump administration — to brand warnings about the former president's policies.

Why it matters: The statement is by no means definitive since, as tweeters immediately pointed out, he could still give to a super PAC or another fund that benefits a candidate.
Former Florida GOP chair Christian Ziegler will not face charges over his recording of a sexual encounter with a woman who accused him of assaulting her, prosecutors said Wednesday.

When Cerberus Capital Management bought an unprofitable Massachusetts hospital chain in 2010, many viewed the deal as a financial lifeline. Now some believe it was actually a noose.

Former UN Ambassador Nikki Haley won Vermont's Republican primary, AP projects, in a contest that was widely seen as her best shot at victory on Tuesday given the state's moderate voter base.

Democratic Rep. Adam Schiff and Republican Steve Garvey topped the primary field in California's U.S. Senate race Tuesday, advancing to a November general election.
Why it matters: The second place finish by Garvey, a Major League Baseball legend, makes it likely that solidly-Democratic California will send Schiff to the Senate next year.

Sen. Kyrsten Sinema's (I-Ariz.) decision not to seek re-election has dealt the latest in a series of crushing blows to Senate bipartisanship, hollowing out a centrist core that has suffered under years of intensifying polarization.
Why it matters: The departures of Sinema, Sen. Joe Manchin (D-W.Va.) and Sen. Mitt Romney (R-Utah) — three moderates routinely vilified by their own parties — will leave a massive hole for bipartisan deal-making.
