Rep. Chris Pappas (D-N.H.) holds a sizable cash advantage over his GOP rivals in the race for New Hampshire’s open Senate seat.

The Democrat raked in $3.3 million to his campaign account over the first quarter of the year as he vies to succeed retiring Sen. Jeanne Shaheen (D-N.H.). Pappas, who faces only nominal opposition for his party’s nomination, entered April with $4.2 million in his war chest, according to his Federal Election Commission filing.

Pappas’ leading GOP competitor, former Sen. John E. Sununu, raised $1.1 million directly to his campaign account and had nearly $1.9 million in cash on hand. He spent just $349,000, per his filing — a significantly lower burn rate than Pappas, who spent $2.3 million over the last three months.

Sununu’s primary rival, former Sen. Scott Brown, lagged even further behind. Brown raised a modest $321,000 and entered the second quarter with $783,000 in his campaign coffers. He spent more money than he brought in, according to his filing.

Pappas leads both of his potential Republican opponents in hypothetical polling match-ups of the general election, though his margin against Sununu is slimmer.

Sununu, who has the backing of the national GOP establishment and President Donald Trump in a state Republicans hope to flip, holds a wide lead over Brown, a former Trump ambassador, in polls of the GOP primary.

Rep. Andy Barr maintained his cash advantage over his GOP rivals in the race to succeed retiring Sen. Mitch McConnell in Kentucky.

Barr raised nearly $1.5 million over the first three months of the year and started April with almost $4.2 million in his war chest — more than five times that of his next-closest rival, according to filings from the Federal Election Commission.

Businessman Nate Morris reported raising $1 million and had roughly $580,000 in his campaign coffers to start the second quarter. But nearly half of that — $450,000 — was a personal loan, per his filing. Morris has now loaned himself $4.9 million over the course of the campaign.

Former state Attorney General Daniel Cameron posted another modest haul; he raised $456,000 and had roughly $765,000 in cash on hand.

Barr holds a slim lead in public polling of the contentious primary for McConnell’s seat that has seen all three major candidates scramble to distance themselves from their former boss and embrace Donald Trump. The president has not endorsed in the race.

Former Rep. Mary Peltola’s (D-Alaska) staggering first-quarter haul comes with a caveat: She spent a lot to raise a lot.

Peltola hauled in nearly $8.7 million directly to her campaign account over the first quarter of the year in her quest to unseat Alaska GOP Sen. Dan Sullivan. She raised four times as much cash as the incumbent, according to filings from the Federal Election Commission. But she spent nearly $3 million, leaving her with $5.7 million in cash on hand.

Sullivan, meanwhile, raised $1.7 million directly to his campaign account and kicked off April with more than $7 million in his war chest.

Both campaigns have argued they’re in strong financial positions in what is already shaping up to be an expensive race by Alaska standards — one that could help decide control of the Senate. Peltola has an early polling advantage and led Sullivan by 5 percentage points in a mid-March Alaska Survey Research poll.

The candidates are getting a boost from outside groups. Democratic-aligned groups have already put more than $3 million into backing Peltola, per the tracking firm AdImpact. The Senate Leadership Fund, a top GOP super PAC, has pledged to put $15 million into defending Sullivan’s seat and has already placed millions of dollars in ad buys.
