U.S. Senator from Maine Susan Collins (R) wrapped up the 118th Congress last week without missing a single vote, extending her nearly three decade perfect voting streak that began when she first took office in the late 1990s.

Sen. Collins, 72, first cast a vote in the U.S. Senate on Jan. 22, 1997, when she voted to confirm Madeline Albright as U.S. Secretary of State — the first woman to hold that cabinet position — under President Bill Clinton.

That same day, Collins also voted to confirm the appointment of former U.S. Senator from Maine Bill Cohen as President Clinton’s Secretary of Defense.

Just under 30 years later, Collins’ perfect voting steak now stands at 9,194 consecutive roll-call votes.

“No one works harder than the people of Maine, and I have always sought to reflect that dedication by showing up to ensure our state is represented in the Senate for every single vote,” Collins said in a Monday press release.

“Representing the State of Maine in the Senate is an honor, and I will continue to approach each day of my service with the diligence and responsibility that Mainers deserve,” Collins said.

Collins’ unbroken voting stretch in the Senate is second only to former Sen. William Proxmire (D-Wis.), who cast 10,252 consecutive votes between 1966 and 1988.

Coming in third place after Maine’s senior U.S. Senator is Sen. Chuck Grassley, the oldest senator at 91 years old, who cast 8,927 uninterrupted votes between 1993 and 2020.

With her perfect attendance record, Collins carries on the legacy of Maine’s Margaret Chase Smith, the first woman to serve in both chambers of Congress.

Smith maintained an unbroken voting record for 13 years during her tenure in the Senate, even famously shirking treatment for a broken arm to avoid missing a vote. Her streak of 2,941 consecutive votes, ending in 1968, set a benchmark for legislative diligence.
