Alaska - Ted Stevens(R) slightly ahead with absentee ballots still to be counted - should Stevens hang on, he will likely lose his seat due to a felony conviction (failure to disclose gifts). Should that occur, a special election would be held within 60 days of the vacancy to fill the seat.
Georgia - Saxby Chambliss(R) won by 3 percent, but failed to garner in excess of 50% of the vote. Under state law, a runoff election will occur on Dec. 2nd. Chambliss is favored in the runoff, but not a shoo in.
Minnesota - Norm Coleman(R) won by 725 votes - however that lead has mysteriously shrunk to 206 due to the discovery of extra votes for Franken - even though the recount is not until Nov. 19th.
Why do we care? Right now, republicans hold 40 seats. They need at least one more seat to even remotely posses the threat of a filibuster. Realistically they need all three to actually be able to wield that club.
While I remain skeptically hopeful (don't know if that makes sense) that Obama may on occasion attempt to reach across the aisle - I'm sure it wouldn't be to hard for him to reach Olympia Snowe (R-ME) or Arlen Spectre (R-PA) - he would have absolutely no reason to even try without that threat.
Without the potential for filibuster, I am certain Majority Leader Reid and Speaker Pelosi will not even look in the direction of the GOP minority. Even if 2010 provides a chance for GOP redemption, alot of bad can happen in two years.
