I do not think having a mistress is so much of a problem for Obama. The real issue is whether or not Obama used Senate campaign funds to subsidize his mistress ala Jonathan Edwards.
Former US Senator Carol Moseley Braun of Illinois (another failed presidential candidate) effectively derailed her political career by putting her boyfriend on the campaign payroll and mixing with dictatorial African thugs.
Obama has not learned the same lesson. Too bad.
No, the REAL issue is whether this chick is sitting off shore processing all those phony credit cards fueled with foreign money.
