We’re destined to find out whether the Republican minority in the U.S. Senate can break the record number of filibusters they set in 2007 and 2008.

Republican incumbent Saxby Chambliss dramatically improved on his November 4 showing to win the runoff Senate election in Georgia by at least 10 points. The result doomed Democratic hopes of a 60-seat majority in the upper chamber.

It’s disappointing but not too surprising. Chambliss would have won outright on November 4 if not for Georgia’s unusual state law requiring the winner to receive 50 percent of the vote. Furthermore, Chambliss would have received 50 percent if not for extremely high black turnout with Barack Obama at the top of the ticket, which benefited Democratic Senate candidate Jim Martin. Also, a Libertarian candidate won enough votes from Georgia conservatives last month to keep Chambliss from winning a majority.

I appreciate the tremendous campaign that Martin ran, which made a race out of what was supposed to be a Kansas or Oklahoma-style romp for the incumbent in this very red state. Unfortunately for Martin, turnout was light today, especially among black voters any Georgia Democrat needs to have a chance of winning a statewide election.

Democrats still have a chance to gain a 59th seat in the Senate, depending on what happens this month in Minnesota. The state canvassing board will consider thousands of challenged ballots, and the margin between Al Franken and Norm Coleman appears to be very slim. The outcome may depend on whether more than 1,000 absentee ballots that were rejected because of clerical errors are counted. Many observers expect this contest to end up in court. It’s also possible that the U.S. Senate could get involved, as it did following an extremely close and disputed Senate race in New Hampshire in 1974.

Don’t despair, Democrats: we still have a decent number of Senate pickup opportunities in 2010. Just today, Florida Republican Mel Martinez announced that he does not plan to run for re-election.

As you’ve no doubt heard by now, Mark Begich took the lead as the early votes were counted, and seven-times-indicted Ted Stevens has conceded the Alaska Senate race. That makes seven Democratic pickups, with Georgia and Minnesota yet to be determined. The Democrats hold 56 Senate seats, and two independents (Joe Lieberman and Bernie Sanders) also caucus with Democrats.

The polls in Georgia have shown Republican Saxby Chambliss ahead of Jim Martin by three or four points. It’s all going to come down to turnout–I doubt much voter persuasion will occur between now and December 2. Barack Obama moved his field staff from Ohio down to Georgia, and many other groups, like Democracy for America, are helping Martin too. The state’s largest newspaper has endorsed Martin.

Chambliss has to be favored in this red state, but if the Democrats have a superior GOTV effort, Martin could pull off an upset.

The Minnesota recount has begun. Al Franken went into it 215 votes behind Norm Coleman (out of more than 2.5 million cast, or 0.008 percent). As of Wednesday evening, he had narrowed the gap to 181 votes. The state has a good “voter intent” law, meaning that if a person can determine the voter’s intent, the vote will count even if an optical scanner did not record it.

I can’t say I feel overly confident, but this study suggests Franken may have a good chance of taking the lead during the recount.

One wrinkle is that Franken successfully sued to get information about voters whose absentee ballots were rejected in one county. His campaign wants that information for all of the counties so that wrongfully excluded absentee ballots can be counted. However, it’s not clear whether those votes will ever be counted, even if the ballots were rejected because of clerical error.

As for the House races, we narrowly lost in CA-44, a district we did not target that was not considered competitive.

CA-04 has still not been called, but Democrat Charlie Brown trails carpet-bagger Tom McClintock by about 600 votes, and it seems unlikely he will be able to make up that margin.

It looks like we will pick up VA-05, which was viewed as quite a longshot before the election.

Louisiana will hold two runoff elections in December. Corrupt Democrat “Dollar Bill” Jefferson will most likely hold the second district. The fourth district is competitive, and Dick Cheney recently headed to Shreveport to campaign for the Republican.

UPDATE: I forgot Ohio’s 15th district, which is going to count provisional ballots. It seems like Democrat Mary Jo Kilroy has a decent chance of beating Republican Steve Stivers.

Democrats will end up with something between 255 and 259 House seats out of 438. Not bad at all.

The Democrat challenging seven-time convicted felon Ted Stevens has taken a lead in the Alaska Senate race. OK, it’s only a three-vote lead among some 250,000 votes counted so far, but if I’m Mark Begich, I’ll take it. (UPDATE: Begich now leads by 814 votes out of some 263,000 counted.)

There are lots more early votes to be counted in the coming days, and no one seems to know exactly where they will come from. However, speculation in this thread at Swing State Project indicates that Democrats have reason to be optimistic about picking up the Senate seat from Alaska. That would bring the Democratic caucus to 58 (counting independent Senator Bernie Sanders of Vermont, who votes with Democrats).

The Minnesota Senate race between Al Franken and Norm Coleman will go to a recount and may not be decided before the middle of December. According to the latest count, Coleman leads by 206 votes out of more than 2.5 million cast. Nate Silver examines Franken’s prospects from several different angles, and concludes:

The more that I examine this data, the more I’m beginning to believe that the number of reclassifiable ballots may be relatively low, but that the proportion of such ballots that are resolved in Franken’s favor may be relatively high. How these two factors will ultimately reconcile themselves, I don’t know.

The runoff Senate election in Georgia between incumbent Saxby Chambliss and Democrat Jim Martin will take place on December 2. There have not been any public polls yet in this race since the general election. A lot of Barack Obama’s field staff have reportedly moved to Georgia to work this race for Martin. The Republican playbook is to link Martin to Democratic leaders in Congress. Will that be enough for Chambliss in this red state?

At Swing State Project, Crisitunity published this overview of likely candidates to replace Joe Biden as U.S. Senator from Delaware. Biden’s son Beau, the attorney general of Delaware, is ineligible because of his current deployment. The most likely options are either Lieutenant Governor Jack Carney, or a seat-warmer who would let Beau Biden run for the seat in 2010, after his deployment has ended.

Speculation about Barack Obama’s replacement continues, with the first Illinois poll on the topic showing Representative Jesse Jackson, Jr. as the most popular choice.

Six U.S. House races are still uncalled: Alaska’s at-large seat, California’s fourth district, California’s 44th district, Ohio’s 15th district, Louisiana’s second district, and Louisiana’s fourth district. The first four are Republican-held seats where the Republican candidate leads. LA-04 and LA-02 will hold runoff elections in December. Probably our best chance to pick up another seat is in OH-15.
