Democrats are expressing optimism about expanding their reach in the Senate over the next few years. They are considering the possibility of achieving a 60-seat supermajority in upcoming elections.
As of 2026, 35 Senate seats are up for election. Of these, 16 are currently held by Democrats and 19 by Republicans. An additional 38 Democratic seats and 25 Republican seats will not be contested. This configuration provides Democrats with a significant opportunity to enhance their Senate presence.
Sens. Bernie Sanders of Vermont and Angus King of Maine, both independents, tend to align with Democratic policies. The outcomes of the 2026 Senate races in Alaska and Mississippi remain uncertain.
Looking ahead to 2028, the situation is similar. Another batch of 35 Senate seats will be up for election. This includes 16 Democrats and 19 Republicans vying for re-election, while 38 Democratic and 25 Republican seats will remain secured from the earlier term.
The Democrats are hopeful to see their majority grow to a range between 54 and 56 seats, contingent upon the still-undecided races in Alaska and Mississippi in 2026. Such developments keep Republicans on edge as they regroup from recent contests.
