FILE – In this Monday, July 4, 2011 file picture, Republican presidential candidate, former House Speaker Newt Gingrich waves while walking in a Fourth of July parade in Clear Lake, Iowa. Since aides and advisers resigned in early June, Newt Gingrichâs presidential bid has been on life support. And his first campaign finance disclosure provided little reason to be optimistic. Gingrich has raised $2.1 million since getting into the race earlier this year, badly trailing front-runner Mitt Romney. (AP Photo/Charlie Neibergall)
