Newt Gingrich’s ad campaign against front-runner Mitt Romney has been all about attacking his record at the private equity firm Bain Capital. Most recently, a pro-Gingrich super-PAC released a 28 minute film called “When Mitt Romney Came to Town” which portrays Romney as a “corporate raider” whose policies ran four companies into the ground for his own benefit. Given Republicans’ long legacy of running on pro-business platforms and promoting laissez-faire legislation, this recent turn is highly ironic. But how the nominees are articulating these sentiments are decidedly different from their liberal counterparts. Dean Baker is co-director of the Center for Economic and Policy Research.
