Sen. Jacky Rosen (D-NV) raised $5 million in the first quarter of 2024, the largest sum of any Senate candidate thus far.

Rosen’s $5 million quarter was not just her best of the cycle; it’s the best first quarter in U.S. Senate history in Nevada, beating out the record Sen. Catherine Cortez Masto (D-NV) had set in 2022 with $4.4 million.

In the fall, Rosen posted a $3.2 million quarter.

Rosen’s haul was more than double that of Republican frontrunner Sam Brown, who raised $2.2 million in the first quarter — his best quarter thus far as well — according to Fox News. Heading into April, her campaign had $13.2 million in cash on hand, a Nevada record for this point in the cycle. 

That war chest is getting poured into a $14 million ad reservation Rosen placed Thursday to run spots on television from late July through the election. Typically, those ad buys do not need to be paid upfront.

Details on Rosen’s donor base and campaign spending will be released by April 15, the Federal Election Commission’s quarterly finance deadline. The Rosen campaign said her average donation size this quarter was $31.75 and more than 27,500 contributions were from first-time donors to her campaign.

The junior senator is one of seven Democrats running to defend seats in competitive races, making the race crucial for control of the Senate. The Cook Political Report moved the race from the “Lean Democrat” to the “Toss-Up” category Wednesday, underscoring how tight the contest is expected to be and how much political spending — from the campaigns and outside groups — will come into the state because of it.
