It's been a long time since Rep. Randy "Duke" Cunningham (R-CA) resigned his Congressional seat in disgrace and the man that bribed him-Mitchell Wade-was convicted. Three years to be exact and Wade is finally about to be sentenced.   His lawyers are now trying to get Wade out of serving any jail time by saying he's provided tips to investigators about other current and former members of Congress, including Sen. Dan Inouye (D-HI), Rep. Alan B. Mollohan (D-WV), Rep. Jerry Lewis (R-CA), Rep. Virgil Goode (R-VA), and Rep. Katherine Harris (R-FL).   ProPublica hashes out what some of these allegations may be against these six members. And while it's great Wade has been willing to help, Wade did a lot of bad things, including $1.8 million in outright bribes to Cunningham.   Maybe an extra helping of potatoes at dinner time makes sense, but I'm not sure a get out of jail free card is the right answer.
