Here's today's run-down of the Congressional races:

Mahoney's Re-Election Chances Downgraded
In a move that shouldn't really surprise anybody, the pundits are reclassifying Congressman Tim Mahoney's (D-FL) re-election chances in the wake of revelations that he had an affair with a former staffer and allegedly paid over $121,000 in hush money. Stuart Rothenberg has changed the race from from "Toss-UP/Tilt Democratic" to "Pure Toss-Up," and Charlie Cook has shifted it from "Lean Democratic" to "Lean Republican."

Another Poll Shows Al Franken Ahead In Minnesota
The new Quinnipiac poll in Minnesota gives Al Franken a slender lead in the Minnesota Senate race: Franken 38%, Sen. Norm Coleman (R) 36%, and Independence Party candidate Dean Barkley at 18%, with a ±3% margin of error. Quinnipiac's previous poll from three weeks ago gave Coleman a 49%-42% lead in a two-way race, but a lot has happened since then with the economy. It should also be noted that a recent Rasmussen poll did not show Barkley definitively siphoning more votes from one major candidate or the other.

Dem Chances Go Up In Oregon Senate Race
CQ has changed its rating on the Oregon Senate race from "Leans Republican" to "No Clear Favorite," citing Democratic strength in the state and the failure of incumbent Sen. Gordon Smith (R) to post a strong lead in the latest polls. In addition, Pollster.com now classifies the race as leaning Dem in the wake of new poll data that shows Democratic candidate Jeff Merkley ahead.

Poll: Hagan's Lead Shrinks In North Carolina Senate Race
The new numbers from Public Policy Polling (D) show the North Carolina Senate race tightening: Dem candidate Kay Hagan 46%, incumbent Sen. Elizabeth Dole (R) 44%, within the ±2.8% margin of error. The previous poll from a week ago gave Hagan a 49%-40% lead. From the pollster's analysis: "Most of the movement has come among Democratic voters, an indication that conservatives who often cross over to vote Republican in federal elections are perhaps being swayed by Dole's attacks on Hagan."

Poll: GOP Congressman Trailing By Seven
A new Research 2000 poll shows Rep. Phil English (R-PA) trailing Democratic challenger Kathy Dahlkemper by a margin of 48%-41%. This corroborates a SurveyUSA poll from two weeks ago that had Dahlkemper up 49%-45%.

Poll: Mark Udall Well Ahead In Colorado Senate Race
The new Quinnipiac poll gives Senate candidate Mark Udall (D-CO) a 54%-40% lead over Republican candidate Bob Schaffer, in the race for this open GOP-held Senate seat. Colorado used to be a state with a serious Republican lean, but has been trending Democratic in recent years -- and the possible Democratic wave this year is only helping Udall that much more.
