(CNN) – Several key races are still undecided Wednesday as ballots continue to be counted.
In the Presidential race, North Carolina, Indiana, and Missouri all show Obama and McCain within one percentage point of each other. All three were previously viewed as critical battleground states for both candidates. However, with Obama leading by 175 electoral votes, the 37 votes no longer hold much sway.
Four seats in the Senate have yet to be determined. As of this morning, Alaska Sen.Ted Stevens was just one percentage point ahead of Democrat Mark Begich and Oregon Senator Gordon Smith had a two point lead on Democrat Jeff Merkley.
In Minnesota Sen. Norm Coleman was 570 votes ahead of Democrat Al Franken. This tight margin falls within Minnesota's recount law, and a recount is now scheduled to take place from mid-November through early December.
Georgia Senator Saxby Chambliss had a four point lead over democrat Jim Martin. Although Georgia’s incumbent leads by four points, state law dictates that in order to win the seat, a candidate must attain over 50 percent of the vote. If this does not happen, an automatic runoff will be held between the top two contenders in early December.
With the Democrats currently holding 56 seats in Senate, these four states will determine whether or not the Democrats reach their goal of a filibuster-proof Senate majority.
President-elect Obama and Vice President-elect Biden's Senate seats will also be vacated, but their replacements are still unknown.
