The Democratic Senatorial Campaign Committee plans to spend $40 million in 10 key battleground states on organizing, voter contacts, and research as part of the party's push to regain control of the upper chamber.

The effort includes Georgia, Michigan, and New Hampshire, where the party is defending seats, and Ohio, Maine, North Carolina, Iowa, Texas, Alaska, and Florida, where Democrats are on offense, Politico reported Tuesday.

"Democrats have expanded the battleground map and created multiple pathways to win a Senate majority, thanks to strong candidate recruitment, formidable campaigns, weakened Republican opponents and a winning message that focuses on the needs and demands of working families across America who have been left behind in Republicans' priorities," Senate Minority Leader Chuck Schumer, D-N.Y., and DSCC Chair Sen. Kirsten Gillibrand, D-N.Y., said in a joint statement. "Today's announcement allows us to build on our momentum."

The funds are earmarked for staff, offices, outreach to minority voters, and volunteer programs rather than expensive advertising buys, the committee's announcement said.

The investments could help push back against Republican super PAC money expected to come later this fall.

Democrats will need to gain four seats to take back control of the Senate. To do so, they will need to win at least two seats in states that President Donald Trump carried by double digits in the 2024 election.

Michigan and Georgia both backed Trump in 2024, while just one of the seats the party hopes to flip — Maine — was won by then-Democrat nominee Kamala Harris.

Meanwhile, the party has faced complications during this summer's primaries, including a last-minute change to Maine's ballot after nominee Graham Platner dropped out of the race earlier this month.

However, polling shows close races and some slight leads for Democrats in the red states of Iowa, Alaska, and Texas.
