(CNN ) - As of 5:00 a.m ET, several Senate races remain unresolved in the 2010 midterm elections. As votes are still being tallied, the estimates contained in this article are subject to change.
Three contests have not yet been projected in the Senate.
Alaska – In the soap opera that is the Alaska Senate race, the write-in votes are at 39 percent, Republican candidate Joe Miller is at 36 percent and Democratic candidate Scott McAdams is at 25 percent with roughly 68 percent of votes reported. Alaska Republican Sen. Lisa Murkowski, who lost her primary bid to Miller, ran as a write- in candidate. However, the write-in votes will be assigned after the original ballot count takes place and only if the Division of Elections determines it needs to tabulate the write-in votes by candidate. CNN has projected McAdams will finish third in this race. This leaves Murkowski and Miller still vying for the seat, but the Republicans can put a check in their column.
Colorado – Republican candidate Ken Buck holds a 49-47 percent lead over incumbent Democratic Sen. Michael Bennet with 81 percent of votes reported. But some of the outstanding votes are in districts that traditionally swing to the Democrats.
Washington state - Incumbent Sen.Patty Murray is dead even with GOP challenger Dino Rossi with roughly 50 percent of votes reported. The contest may not be resolved for several days to a week, state election official Dave Ammons told CNN. Of Washington's 39 counties, 38 of them vote by mail, and ballots will be counted if they are postmarked on or before Election Day. Thus, thousands of ballots have yet to be counted.
BALANCE OF POWER:
CNN projects that the GOP has picked up six seats in the Senate - North Dakota, Wisconsin, Arkansas, Illinois, Indiana and Pennsylvania - which brings the Republican's total to 47 seats. If the Republicans win Washington and Colorado, they will bring their net gain to 8 seats.
The Democrats will keep the Senate, CNN projects, and currently stand at 51 seats - a majority - with Washington and Colorado undecided.
