Lefties are aglow as protests spread like a rash through Manhattan and other big cities, sure this is just what their side needs. The offensive protesters took them off the defensive. This is their first jolt of speed since Grant Park and Barack Obama. After many false starts, this is their Tea Party. If they can turn mobs out, what can’t they do next?

For one thing, they could mobilize, organize and elect their own candidates. They could elect a really left-wing and liberal president, and huge majorities in the House and the Senate, and have them fix everything.
