“Sens. John Fetterman (D) and Dave McCormick (R) of Pennsylvania have set up a joint fundraising committee, according to a Federal Election Commission filing, a rare move for lawmakers from opposing political parties,” the Washington Post reports.”With joint fundraising committees, two or more candidates, party committees or PACs can raise money together, and donors can write a single big check rather than several smaller ones. Presidential candidates have historically used joint fundraising committees to bulk up their war chests ahead of general elections. It’s unusual for the participants to be affiliated with different political parties.”
