A man in a wheelchair shouted at those headed inside: "Look at all of you - socialists! Shame on you guys!"
An Obama supporter, also in a wheelchair and with a missing arm, yelled back. "Who bought your wheelchair?"
They bring a guy in a wheelchair, you bring a guy in a wheelchair missing an arm. That's the Chicago way!
For some reason this exchange also reminds me of an NHL bench clearing brawl where the two goalies end up squaring off. Unlikely combatants, not something you see every day.
