The good thing about stuff like this...it sure draws the palin haters out....
However, I do think Alaskans are a pretty dramatic and emotional bunch....their environment alone would be enough to facilitate that. They laugh loud and hard, play loud and hard...and cry loud and hard. It's their culture sort of thing.
Furthermore, it was a party with booze, music and celebration....and unwanted people arriving at anyone’s party would set the stage for the unexpected.
No big deal in my book....I suspect if Washington Representatives home-life were on stage we'd find as much and likely more harrowing episodes.
