that gives current odds on all the upcoming races, updated often.
http://www.campaignline.com/oddsmaker/index.cfm?navid=12I took the odds they give for all Senate races and used them to calculate the probabilities of Democratic party gaining or losing Senate seats in 2006. Here are the inputs (I assumed that Jeffords would win, in order to narrow it to D/R only)
The probabilities in the individual Senate races:
Democratic Senate Seats Win Probability|Republican Senate Seats Win Probability
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~|~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
California - Dianne Feinstein 80.0% | Arizona - Jon Kyl 75.0%
Connecticut - Joe Lieberman 90.0% | Indiana - Richard Lugar 88.8%
Florida - Bill Nelson 54.6% | Maine - Olympia Snowe 87.5%
Hawaii - Daniel Akaka 88.8% | Mississippi - Trent Lott 83.3%
Maryland - Open 54.6% | Missouri - Jim Talent 57.2%
Massachusetts- Ted Kennedy 88.8% | Montana - Conrad Burns 60.0%
Michigan - Debbie Stabenow 54.6% | Nevada - John Ensign 66.6%
Minnesota - Open 50.0% | Ohio - Mike DeWine 60.0%
Nebraska - Ben Nelson 52.6% | Pennsylvania- Rick Santorum 52.7%
New Jersey - Open? 60.0% | Rhode Island- Lincoln Chaffee 51.7%
New Mexico - Jeff Bingaman 60.0% | Tennessee - Open 51.7%
New York - Hillary Clinton 75.0% | Texas - K. B. Hutchinson 66.6%
North Dakota - Kent Conrad 60.0% | Utah - Orrin Hatch 87.5%
Tennessee - Open 60.0% | Virginia - George Allen 75.0%
Washington - Maria Cantwell 52.6% | Wyoming - Craig Thomas 88.8%
West Virginia- Robert Byrd 80.0% |
Wisconsin - Herb Kohl 70.0% |
Here are the outputs:
Probabilities of gaining seats:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Democrats | Republicans
# of | | # of |
seats | Probability | seats | Probability
gain | (in %) | gain | (in %)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
9+ | 0.0 | 9+ | 0.2
8+ | 0.0 | 8+ | 0.6
7+ | 0.1 | 7+ | 1.7
6+ | 0.3 | 6+ | 4.3
5+ | 1.1 | 5+ | 9.4
4+ | 3.0 | 4+ | 18.0
3+ | 6.9 | 3+ | 30.3
2+ | 14.0 | 2+ | 45.4
1+ | 24.8 | 1+ | 61.1

0 | 14.1 | 0 | 14.1
So, the probability of Democratic Party taking the Senate next year, according to the individual race odds from that Web site, is 1.1%. (or, if you feel that Democrats need 51 seats in the Senate to "take it", the probability is 0.3%).
