Historically, it's been alleged that some 'celibate' Catholic bishops fucked women. When the resulting bastard children grew up, they were rewarded with coveted Church appointments. If anyone noticed the apparent favoritism, they blamed the adultery on their brother, saying the appointee was a nephew (it: nipote) rather than the priest's own illegitimate son. Thus the origin of the term nepotism.
Probably some of them had different tastes and realized that fucking boys leaves less evidence.
I used to live in Ohio, and had three presidential candidates visit close enough to conveniently get to. I went to the Edwards, Obama (primary season), and Romney events. I didn't order advance tickets for any of them. Both Democrats had volunteers outside the security trying to get everyone who showed up with or without tickets through security and into the main venue. At Romney's I didn't get in and just loitered around the outside fencing. That might have been the better experience -- I could still hear the speeches, and the outside crowd had better signs and more colorful commentary than the inside ones.
