AFP: Gleeful Democrats fanned the flames Thursday after Republicans did President Barack Obama's dirty work for him and savaged their likely 2012 nominee Mitt Romney as a "vulture capitalist." An explosion of vitriol from rivals Newt Gingrich and Rick Perry in recent days, thrust Romney's past as a Wall Street equity kingpin into the heart of the presidential campaign. Democrats piled on, painting the man they expect to face in November's polls as a poster boy for the corporate excess that many Americans blame for plunging their nation into the economic mire.
