2026 Midterm Elections Put U.S. Senate and State Legislative Control at Stake

Both parties are actively targeting Colorado’s legislature: the Democratic Legislative Campaign Committee is focusing on five state Senate districts, while the Republican State Leadership Committee is targeting Colorado as one of eight states where it aims to protect its members.
The DCCC said candidates added to its “Red to Blue” program would receive strategic guidance and fundraising support; the six districts were won handily by Donald Trump in 2024.
Democrats replaced their Maine Senate nominee in July with former state Sen. Troy Jackson, according to NPR’s election coverage.
Pennsylvania Democratic Senate candidates Eileen Hartnett Albillar, Mark Pinsley and Chris Thomas are emphasizing affordability, amid voter dissatisfaction with President Donald Trump’s handling of the economy and gas prices. Bucks County Democratic chair and state Sen. Santarsiero said the races would, “to one extent or another,” become a referendum on Trump.
If Democrats flip the Pennsylvania Senate while retaining their state House majority, they could create a Democratic trifecta in Harrisburg, giving Gov. Josh Shapiro an opportunity in a second term to advance his agenda.
Democrats are seeing fresh opportunities in the 2026 midterms, with competitive races emerging in traditionally Republican strongholds like Texas, Alaska, and Ohio. Ballotpedia reports that the party is targeting state legislatures and U.S. Senate seats across the country, signaling confidence despite the uncertainty of any election. From Colorado to Pennsylvania to Maine, Democrats believe they can flip chambers and reshape power in key states.
The Democratic Congressional Campaign Committee added six Republican-held House districts to its "Red to Blue" program, San Luis Obispo reported, a designation reserved for races Democrats believe they can win. These districts were all won decisively by Donald Trump in 2024, yet Democrats see openings. Party strategists are pouring money and expertise into these races, banking on voter frustration over the economy and other issues to swing seats their way.
Colorado Democrats currently hold a 23–12 majority in the state Senate, according to Ballotpedia, but they need just one more seat to secure a supermajority. That power would let them pass legislation without any Republican support. The Democratic Legislative Campaign Committee is focusing on five state Senate districts to reach that goal, while Republicans are fighting hard to block it.
Republicans understand the stakes. The Republican State Leadership Committee is targeting Colorado as one of eight states where it aims to protect its members and stop a Democratic supermajority. Elections for 18 of the 35 Senate districts will happen on November 3, 2026. Each side is treating this as a do-or-die battle for control of a state that has trended Democratic in recent years.
Pennsylvania Democrats are targeting three Republican-held state Senate districts, NPR's election coverage reports. To control the chamber for the first time since 1991, they must flip at least two of those seats while keeping Gov. Josh Shapiro in office. Shapiro is running for reelection against Republican Stacy Garrity. A Democratic sweep would give Shapiro a "trifecta"—control of both chambers—in his second term.
Three Democratic Senate candidates—Eileen Hartnett Albillar, Mark Pinsley, and Chris Thomas—are hammering Republicans on affordability and the economy. Bucks County Democratic chair and state Sen. Santarsiero said the races would become "to one extent or another" a referendum on Trump. Voters are dissatisfied with the president's handling of costs and gas prices, giving Democrats an opening to expand their power.
Maine's U.S. Senate race is shaping up as a true battleground. Republican incumbent Susan Collins is defending her seat in a state NPR notes that Kamala Harris won in 2024. Democrats replaced their original nominee in July with former state Sen. Troy Jackson, a fresh face with room to build name recognition before Election Day in 2026.
Jackson faces a real challenge raising his profile and fundraising against Collins, who is a well-known incumbent. But the state's Democratic lean gives him a path to victory. This race could help determine which party controls the U.S. Senate after 2026, making it a national priority for both Democrats and Republicans alike.
The DCCC's decision to add six House districts to the "Red to Blue" program shows Democrats are thinking boldly. These six districts all voted for Trump in 2024 by comfortable margins. Yet Democrats believe shifting voter sentiment on the economy and other issues creates opportunities to flip them from red to blue.
Candidates added to the program get strategic guidance and targeted fundraising support from national party leadership. The DCCC doesn't add races lightly—the designation signals real confidence in Democratic prospects. If Democrats can flip even some of these districts while making gains in state legislatures, they could reshape power from coast to coast by 2027.
