Recent reporting and announcements directly related to this race and its candidates.
Recent polls keep the Maine Senate race very close, with Troy Jackson slightly ahead or tied with Susan Collins. Collins also picked up a Joe Manchin endorsement, while a report on private jet spending and scrutiny of Jackson’s property comments add mixed campaign headlines. The race still looks highly competitive, with recent polling offering no clear leader. The Manchin endorsement may help Collins at the margins, while the spending report and Jackson scrutiny add mixed, limited movement.
In order to flip the Senate, Democrats need to keep control of their 47 seats and gain four more.

The party is in the midst of a remarkable comeback—mostly thanks to one man.

Whether you're planning to vote Tuesday, still have that absentee ballot sitting on your counter, or are just eager to see how it all shakes out, here's what to expect on Election Day.

Sen. Susan Collins accused Chuck Schumer and Democrats of flooding Maine voters with “outright lies" in attack ads as she faces a tight reelection race against Troy Jackson.
The 2026 election is nearly here, and battles for control of the U.S. Senate and House are continuing to heat up
Approximately 54 million Americans have offered a glimpse into the midterm election, which is seeing an uptick in younger and racially diverse voters.
