Guys, don't any of y'all remember the Chicago convention in 1968?
I'm guessing that there are going to be riots, since the extremist folks won't play nice-nice with the moderates... And if Hillary manages to wrest the nomination from Obama, there are gonna be riots across the country.
Remember - the "activists" will truck in "protestors," whose main goal seems to be breaking things... If they'll get crowds to show up for banking conferences, multiply it a few times for this little shindig.
Obama has heavily recruited the "youth" vote, and really gone after the extremist folks. Plus, there's the race factor - many of his supporters are voting for him purely because of his race, and not looking further.
If Obama gets the nomination, there will likely be "celebrations." Google "basketball riot" for the exact definition. Then, after McCain beats him, there are gonna be some SERIOUS riots...
This is gonna be an ugly election. Stock up on ammo and canned goods, and schedule vacation if you work in a major city.
