Can we drop the debates and get back to the political forecasting?
Regarding the Senate: Currently, it’s 55 R, 44 D, 1 I. So the Democrats need six. However, of the 33 seats up, 18 are currently held by Democrats, and only 15 by Republicans.
Assuming the Democrats hold serve with their 18, the likeliest where they could pick up their six are the following races with GOP incumbents:
Pennsylvania–Santorum ® has trailed Casey badly, although the gap has narrowed recently.
Tennessee–Frist is retiring, so Ford (D) has the name recognition; however, Southern states are not typically too receptive to black Democrats.
Ohio, Montana–Burns and Dewine could each be hurt by their links to the Abramoff scandal, however both lead in the polls. However, both are down towards the bottom in “net approval ratings” as seen here.
Arizona–Kyl ® leads by 10-15 points, but Pedersen lately has been closing the gap.
Nevada–Ensign is a first-term incumbent and they’re the most vulnerable. However, Carter’s campaign hasn’t really gotten any traction yet.
Missouri–Talent fills Missourans with a big heaping bowl of “meh” and could be vulnerable to McCaskill.
Virginia–Allen recently was the subject of a hugely unflattering New Republic profile, and may be distracted by running for the Senate in '06 and the presidency in '08 at the same time. The Democratic primary, where they will choose between Harris and Webb, is in June.
Rhode Island–The moderate Chaffey will have a tougher fight in the primary against conservative Laffey than he will in the general against Whitehouse.
