There had been a pretty incendiary thread on dKos where a lot of this stuff got aired and I was able to do a lot of tracking back to real sources from it.
It turns out that the women allegedly mishandled weren't aware of it, the most you could say is that Bill's "charm" can be misread but, judging by what I remember of it, he did not do anything inappropriate.
Also it was obvious that the people (some miffed local dems) who were churning this rumour had personal grudges against him.
The rumours were/are common knowledge around NM and nobody will touch them. Not even the Repugs. If Drudge or Fox thought they could stand it up, they'd have tried before now. keep to the Fen Causeway
I think the whole thing started due to the normal conversation distance of Hispanos is closer than Anglos feel comfortable with.
Anyway, the rumors don't have to be True to be politically effective.
