RALEIGH, N.C. — There have been four years of civil disobedience, reputation-bruising boycotts over bathroom access, and legal battles over voting laws and gerrymanders. The election for governor, fraught with Republican challenges, took a month to settle.

But if anyone here thought that the Democrat Roy Cooper’s victory in that race would open a new era of cooperation and calm in this bitterly divided state, all they had to do was listen on Thursday to the bellowing voice of Evan Hughes, a lettuce farmer from Durham. Around noon, Mr. Hughes, 35, was in front of North Carolina’s legislative offices with a child in his arms, berating the executive director of the state Republican Party for the group’s gambit to strip Mr. Cooper of many of his powers as governor before he even takes office.

“We’re talking about changing the rules at the last minute,” Mr. Hughes said. “The people of North Carolina are sick and tired of the G.O.P.’s antics — anti-democratic antics. It is embarrassing to the people of North Carolina.”

Dallas Woodhouse, the Republican official, had initially tried to engage Mr. Hughes. But he eventually fled into the building, where lawmakers from his party introduced a flurry of bills during a surprise special session this week to undermine Mr. Cooper by stripping him of his ability to make key appointments to state and local boards and mandating, for the first time, legislative approval of his cabinet.
