Yet another Democrat has announced an exit from politics as the party heads into a contentious midterm season. On Monday, Vermont Senator Patrick Leahy revealed he will not be running for re-election.

The Hill reports:

Leahy, 81, has already served eight terms in the upper chamber. He currently serves as the president pro tempore of the Senate, the second-highest ranking position in the chamber.

A Republican has not filed to launch a bid for Leahy’s seat. Meanwhile, a number of potential Democratic contenders have been floated, including Rep. Peter Welch (D-Vt.); Vermont Senate President Pro Tem Becca Balint (D); state Sen. Kesha Ram-Hinsdale (D); and Lt. Gov. Molly Gray (D). A woman has yet to represent Vermont on Capitol Hill.
