Vicki Iseman. He's now gone on record and denied any romantic affair with her. It would have been bad enough on simple 'infidelity' grounds. But that may have been containable. But she was a lobbyist, so there are serious ethical considerations involved, now. If he's lying, which, given my cynical nature, I believe is very possible, he can kiss an essential base of the GOP goodbye, even if he makes it to the general election. He can also kiss a good % of independent voters, the piÃ¨ce de rÃ©sistance, goodbye, too.
