McCain was a brash, obnoxious, and reckless naval aviator.
I would have little trouble believing accusations including alcohol & womanizing.
BTW, the accusations of such date from his time in the Navy and his first marriage, which ended in the late 1970s/early 1980s, IIRC, while he was in the Navy.
McCain has been married to the Beer Blonde for nigh on 20 years.
He had several affairs IIRC including with the Beer Blonde... the point surely is that he never denied it, accepted the blame and - most importantly - didnt go on about what a great husband he was while simultaneously banging one of his staff, and all the while paying her off out of campaign funds.
Still, I hope anyone who donated to Edwards '08 appreciates that he at least spent their money on something worthwhile.
