New Hampshire Senator Jeanne Shaheen joined on Wednesday the growing list of those who won't be seeking re-election in 2026.

Of the four senators who made such announcements, three are Democrats, the others being Gary Peters of Michigan and Tina Smith of Minnesota. Mitch McConnell is so far the only Republican who won't pursue staying in his seat next year.
