There's no warrior template out of a legion of liberals. Thugs, sure. Bullies, yes. Looters, you name the loot. Fighters, people who can get organized, and face down organized resistance? No. Not a prayer for that. There's million combat vets from the last ten years, either still in the uniform or out, who are 5 to 1 conservatives. (The 1s being mostly cooks and finance clerks). There's tends of millions of hunters, gun owners, and sport shooters who won't be intimidated by some slack jawed X-Box junkie and his weed smoking, baggy pants wearing cohorts.
Obama and the left want to whip up mobs, but the mobs are by definition full of losers. They want what they can't earn and sure as hell can't fight for. The worst day of their life would be the day they decide to get violent, strike down the police and slip into lawlessness. They have no idea, not an inkling, of what would befall them were they to cast down the law and attack the people directly.
Obama's playbook doesn't recognize this, because in most countries, the mob is power, because the people are not armed. Here, the mob is a threat to peace, and will be put down until law can be reestablished. If Obama had the barest strand of sense, he'd pray he was never successful in whipping the crowds of progressive thugs up into lawless violence.
If this doesn't materialize as a tactic leading up to the election, it's likely to happen as a reaction to an Obama defeat.
Cannot get organized for violent acts? ... Google ‘ELF’ or watch a few of the community organizer organized flash mob videos.
The usual suspects will have the looter brigades out and deployed, ready for the SHTF moment, and then the bagging and burning will start (that's what's in it for them).
In the end, though, the TEA party movement will be villified (More Alinsky), and the Marxists may even use official assets to strat a roundup. From there, all bets are off.
