If you're interested in actually winning elections, instead of feeling good about skunking Obama, or any other Democrat, you're going to need to bring in Independent voters as well, and they just don't care about things like who's sleeping with who. They are the ones who CAN be persuaded by concentrating on the economy, lack of jobs, outrageous government spending, over-reaching by Congress, and sometimes even the social issues.
I don’t think even most Independents would like the idea of a closeted homosexual who has a very shady promiscuous past (and who knows about present), replete with murders and hard drug use!
