I don't know why people find politicians sexy. Terrible stuff, imagine having to listen to all that blather about meetings and whatever else they do. Yes people will say, "oh it's the power" but pfft.. if you want to fall in love with power you need a mafia boss or Khan Noonien Singh not a paper pusher.
They are charismatic and they don't have to talk about that. Antony Weiner is a great standup comic for example.
