Being a sarcastic Hoosier myself and having known Dave since his days as weatherman in Indpls, and being fired every few days, I have to say that it bothers me not.
IF he were harassing women, it would be a problem but since no one has come forward to claim so, and there would be a big monetary reason to say such, I would think it is NOMB.
Many women stalk men with money and position hoping to win the big lottery of becoming and wife of, and future ex wife with big alimony it seems that he must have picked well so that says something about whether it was just a fling or a relationship with the women. Anything over one is plural so it might not be nearly the harem that some might suppose.
Dave's mom is a very down to earth woman and I doubt that anything he has done would shock her.
I frankly do not care about the sexploits of politicians or others either unless they doing it on my dime or time. That is up to their Significant Other, if they have one, to worry about.
Take a look at some of the guys who get into such relationships. Many are not good looking but they have a wallet that attracts or a position.
I would figure that you catch your fish where you throw your line and if you spend most of your time working it is most likely to be there. It can be distracting and problematic and that is why it is discouraged but heck, stuff happens.
I am a firm believer in monotony, umm, I mean monogamy,

but it is not how many folks are caught with their drawers down but how many who are not. Now that is amazing and wonderful!
Must I confess that I stole a book when I was four before someone blackmails me?
I love how Dave handled it. It was a very 'Dave' thing to do. Wish more folk would just fess up and get it over with. Would save us all much grief, especially them, but then the media ratings would suffer greatly.
