The Obama campaign on Tuesday shrugged off reports showing that Republican challenger Mitt Romney outpaced the president by $35 million in contributions last month, even after firing off a dire message to donors warning of defeat in November if fundraising doesn’t improve... Obama representatives also blasted the Republican super PACs. “You’ve got a few very wealthy people running around trying to purchase the White House for Mr. Romney,” White House senior adviser David Plouffe told ABC’s “Good Morning America” on Tuesday.
