WASHINGTON - In the clubby atmosphere of the U.S. Senate, with its premium on going along to get along, Mark Dayton sometimes stood out for going it alone. Not always with happy results.
Now, locked in a three-way battle to be Minnesota's next governor, a long record in public office that spans U.S. senator, state auditor and state economic development commissioner provides much for supporters and foes to say about Dayton.
The two seminal events of his six years in Washington both involved acts that could alternately be cast as profiles in courage or weakness, depending on the partisan spin.
The vote that largely defined Dayton's Senate career came in the run-up to the U.S.-led invasion of Iraq. Dayton and fellow Minnesota Democrat Paul Wellstone were among only 23 senators to oppose President George W. Bush's war powers resolution.
Dayton counts it as one of his proudest moments -- a tough vote that came after a sleepless night of deliberation.
The other event wasn't a vote, but a staffing decision he made two years later while at home in Minneapolis during a congressional recess.
In a move that rankled much of official Washington, Dayton became the sole member of Congress to heed classified warnings of a potential pre-election terror attack in the city. He acted decisively, temporarily closing his D.C. office to spare his young staffers and any visitors unnecessary exposure to danger. The move garnered nationwide press attention -- much of it unflattering -- and has been raised in opposition campaign ads in the current governor's race.
It was easily the biggest rumpus in a long public career that has spanned 35 years.
