Revelations about the conduct of former Representative Mary Peltola, a Democrat, toward her staff — including angry outbursts and the use of slurs — drew criticism on Thursday from Republicans who suggested they showed her unfitness for the Senate seat she is seeking. But it was not clear whether Alaskans, who for decades have elected abrasive, bellicose and occasionally violent individuals to represent them in Congress, would find it disqualifying.

Alaska’s representatives on Capitol Hill have long brought a special brand of coarseness to Washington, part of a frontier mentality and a rough-and-tumble political tradition that comes with a bare-knuckled approach to securing federal resources for their remote state. “In Alaska, abrasiveness can sometimes read as political charisma, or sometimes even as authenticity,” said Alexander Hirsch, a political science professor at the University of Alaska Fairbanks.

Here is a look at a few of the state’s more aggressive characters. Senator Ted Stevens, serving for 40 years, was known as a fierce and often hot-tempered advocate for Alaska. As a member and then chairman of the powerful Appropriations Committee, he funneled billions to his state, including to create the Trans-Alaska Pipeline.

When he faced a tough Senate debate, Mr. Stevens wore a tie featuring the image of the Incredible Hulk. “I’m a mean, miserable S.O.B.,” he proclaimed in 1977 as he took over as chairman of the appropriations panel.
