With 94 of 112 precincts reporting veteran Executive Councilor Ray Burton of Bath has about 71 percent of the votes, easily rebuffing challenger Jerry Thibodeau of Rumney.
Burton had almost 14,500 votes compared to about 5,800 for Thibodeau.
Burton effortlessly put down a revolt by some Republican representatives in the North Country who thought he was too moderate and urged his defeat.
In November Burton will face Democrat Beth Funicella.
Debi Warner of Littleton also won and will be the Republican contender for the North Country's senate seat vacated by John Gallus of Berlin.
With 36 of the 40 precincts reporting Warner had 2,577 votes - or about 63 percent.
She beat Frank Dumaine of Berlin who had about 1,499 votes.
In a statement released early Wednesday morning Warner said she intends "to bring forward good government that listens to people and brings solutions that work for our diverse and hearty district. We must resist the Northern Pass and cultivate businesses that are compatible with our mountains and people. We need to improve our infrastructure and simplify regulations, which I will work to accomplish in Concord."
The budget "must be balanced with compassion," she added.
In November Warner will face Democrat Jeff Woodburn of Dalton.
In Coos District 1 with seven of 10 precincts reporting incumbent Republican Larry Rappaport of Colebrook dominated with 390 votes.
Incumbent Republican Duffy Daughtery of Colebrook had 272 votes and Republican challenger Charles Kurtz of Errol has 247 votes, a relatively strong showing.
Kurtz is hoping to replace either of the incumbents on the November ballot.
In Coos District 7 with all the votes counted Republican challenger Leon Rideout defeated incumbent Bill Remick, 798 to 437. Jeffery Young had 136 votes. Remick had been criticized for not being conservative enough.
The results on race between Coos County Commissioner Bing Judd and Rick Samson were not available.
The statewide votes were collected by the Associated Press.
