Here's the rundown on today's Congressional races: The theme for today is ethics -- and how everyone is saying their opponents don't have any.

House Dems Demand DOJ Get Involved In Miss. Senate Race
A group of Congressional Dems led by House Judiciary chairman John Conyers (D-MI) are now demanding Justice Department intervention in the Mississippi Senate race, where GOP officials are tying to bury the race at the bottom of the ballot. "What we have here is a clear intent to confuse voters," said Mississippi Dem Congressman Bennie Thompson, in a press release from the group.

Dem Candidate Ties Himself To McCain In Deep-Red Kentucky
Bruce Lunsford, the Democratic businessman running against Senate GOP Leader Mitch McConnell (KY) has an interesting strategy in his new ad. Since he's running a state that is likely to go to John McCain by a very wide margin, he's tying himself to McCain's own condemnations of Republican corruption:

"John McCain singled out Mitch McConnell on corruption," the announcer says. In a way, this is essentially the mirror image of Republicans like Sen. Gordon Smith and Rep. Christopher Shays, who have tied themselves to Barack Obama in their much bluer states.

Dems Go Directly After Ted Stevens' Scandals In New Ad
The DSCC's new ad in Alaska goes right after Sen. Ted Stevens (R) for his indictment and other ethical scandals:

"Stevens once used his power for Alaska -- now he uses his power for himself," the announcer says.

Musgrave Alleges Opponent Used Government To Enrich Herself
The campaign of Rep. Marilyn Musgrave (R-CO), a Christian-Right champion who is in serious danger of defeat this year, is accusing her Dem opponent Betsy Markey of using her time as an aide to Sen. Salazar (D-CO) to secure contracts for her family's Internet-service business, which Markey has strongly denied. Musgrave's campaign has not offered any evidence, but said the onus is on Markey to prove she did not abuse the public trust. Here's her ad built around the accusation:

Smith And Merkley Schedule Debates
Sen. Gordon Smith (R-OR) and Dem opponent Jeff Merkley, who are locked in a tight race, have finally agreed to two debates after much haggling on Smith's part. The first one is set for October 9, with the next one just four days later.

Arnold To Hold Fundraiser For Smith

Bachmann May End Up Skipping Debate
A group of citizens in the Minnesota town of Scandia, located in the district of Rep. Michele Bachmann (R), have scheduled a town-hall debate for September 23. One problem: Democratic challenger El Tinklenberg and independent candidate Bob Anderson have accepted the invitation, but Bachmann herself has not yet RSVP-ed.

Libertarian Candidate In Legal Trouble
Kevin Barrett, the Libertarian candidate for Wisconsin's Third District, is now facing a disorderly conduct charge after a domestic incident. Barrett is best known for expressing his skepticism over Osama bin Laden's role in the 9/11 attacks, which he expressed in a class he taught at the state university, and has been endorsed by Jesse Ventura.
