Senate Democrats staring down tough re-election fights can look to one bright spot: sizable fund-raising hauls and cash stockpiles more than a year before Election Day.
In states where they are most vulnerable in 2024 — Montana, Ohio, Pennsylvania, West Virginia and Wisconsin — Democratic incumbents have raised more money than they previously have at this stage in earlier cycles, the latest campaign filings show. Saturday was the deadline for campaigns to file spending and fund-raising reports for the three months between April 1 and June 30.
Most of the vulnerable incumbent Democratic senators also topped their prospective Republican challengers in fund-raising and will head into the fall with several million dollars in cash on hand.
The race for Senate control is in its earliest months, and Republicans are still building campaigns. Yet the Democrats’ relative financial strength in the second quarter of an off year suggests significant energy as the party aims to protect its slim majority next year.
The electoral map, however, will be one of the most challenging the party has faced in years. Nearly two dozen Democratic seats are up for re-election in 2024, with eight incumbents seen as vulnerable, while just 10 Republicans face re-election — and all of the G.O.P. incumbents won by comfortable margins in previous cycles.
In their Senate re-election bids, Sherrod Brown of Ohio and Jon Tester of Montana both brought in more than $5 million. Mr. Brown had $8.7 million in cash on hand, and Mr. Tester $10.5 million. Senator Tammy Baldwin of Wisconsin raised $3.2 million, the most ever raised in a Wisconsin Senate contest in an off year, according to her campaign.
Senator Joe Manchin of West Virginia, a conservative Democrat who has not yet publicly said whether he will run for re-election — and is flirting with a third-party presidential run — raised $1.3 million over the last three months and has more than $10 million in the bank, expanding his cash advantage over Gov. Jim Justice and Representative Alex Mooney, Republicans who have already begun campaigns to unseat him.
In Pennsylvania, Senator Bob Casey posted his best fund-raising quarter to date, bringing in more than $4 million for his re-election bid.
Republicans have been preparing their own money machines and recruiting candidates in five states with vulnerable Democrats. Republican confidence has also been bolstered by the 2024 Senate map.
The Democrats “are trying to use money to defy gravity,” said Stu Sandler, a political consultant and former political director of the National Republican Senatorial Committee. “This is a lopsided map for them,” he added, pointing to former President Donald J. Trump’s 2020 victories in Ohio, Montana and West Virginia — all states Mr. Trump won decisively. And, he said, Republicans have some “very credible favorites” to challenge the incumbents.
Democrats view this fund-raising as a crucial show of strength that will fortify their candidates ahead of a difficult 2024 cycle for the party.
“Voters and grass-roots supporters are once again supporting battle-tested Senate Democratic candidates in record ways because they recognize the stakes of this election and the importance of stopping Republicans from implementing their toxic agenda,” said Tommy Garcia, spokesman for the Democratic Senatorial Campaign Committee.
In Arizona, Representative Ruben Gallego raised more than Senator Kyrsten Sinema, who has changed her party affiliation from Democrat to independent, by two-to-one — the second time this year Mr. Gallego has notched such a ratio. He still trails Ms. Sinema in cash on hand by more than $7 million. Ms. Sinema has not yet announced whether she will run for re-election.
Even Democrats in safe Republican territory had strong showings. In Texas, Representative Colin Allred raised $6.2 million in his challenge to Senator Ted Cruz. Mr. Allred, who announced his campaign in May, brought in more money in a shorter period of time than Mr. Cruz, who raised $4.4 million in the last three months.
