The Alaska Senate might be run by a coalition of Republicans and Democrats for the next two years.
Currently, 11 Republicans and nine Democrats are in the state Senate, with 10 seats at stake in Tuesday's election.
With most of the votes counted, the results of one race - a Republican seat being vacated by Sen. Gary Wilken of Fairbanks - was still unclear.
Democrat Joe Paskvan held a 213-vote lead over Republican Cynthia Henry with all of the precincts in, but with absentee and some early votes still to be counted.
If Paskvan prevails, the Senate will have a 10-10 split between the Democrats and Republicans. That would mean another coalition composed of members from both parties would run the Senate for the next two years, just as it has for the last two.
If Democrats win that Fairbanks seat, it will be the first time they've drawn even with Republicans since 1992.
In the House, the GOP has held a 23-17 lead over Democrats for the last two years.
Incumbents were running in 36 of the 40 House districts, and most won on Tuesday.
But at least one incumbent lost.
In Juneau, Rep. Andrea Doll, a Democrat, lost her seat to Republican Cathy Engstro Munoz.
Two Fairbanks incumbents held narrow leads with all votes counted except the absentees and early ballots. Rep. Scott Kawasaki, a Democrat, led by 87 votes over Republican Sue Hull. And Rep. Mike Kelly, a Republican, held a 137-vote edge over Karl Kassel.
It's likely the Republicans will retain control of the House.
The Senate and the House expect to organize in the week following the election.
