Mrs. Spitzer to blame: Moralist

Professional self-appointed moralist and scold "Dr." Laura Schlessinger tells NBC's The Today Show that Silda Wall Spitzer, the better half of former New York Governor Eliot Spitzer, drove the hubster to expensive extracurricular horizontal mambo-ing by failing to sufficiently submit to Eliot's connubial requirements:

When the wife does not focus in on the needs and the feelings, sexually, personally, to make him feel like a man, to make him feel like a success, to make him feel like her hero, he’s very susceptible to the charm of some other woman making him feel what he needs.

Schlessinger, an Old Testament religious conservative who earned her degree in physiology by methodically picking the legs off of insects, can be viewed catering to a former boyfriend's needs and feelings, complete with 70s porn-bush beaver shots, at this link.*
