You're right, instead of petitions, we'd be having riots in multiple urban locales...
Seriously? That reeks of unsubstantiated and unprovable FUD. I've yet to see any evidence of political outrage among minorities or urban residents on a level that would have fueled riots had the presidential election results been reversed. That's talk radio/borderline Prison Planet/Turner Diaries ********. Fabricated political tension that simply doesn't exist.
Someone might have yelled something stupid or broken something that made a good YouTube clip for the Drudge Report or Breitbart's ghost to pimp, but there wouldn't have been any damn large-scale riots in multiple urban centers. The people that disaffected weren't sitting at home with their last shred of hope tied to an incumbent president.
