Is Newt Gingrich giving up the ghost? His presidential campaign is deeply in debt, his popularity has waned significantly, and everyone in America (besides him) clearly recognizes that Mitt Romney has won the Republican nomination. Yet he’s persisted, trying desperately to frame himself as the “conservative alternative” to Romney’s “Massachusetts Moderate.”

But the campaign has just cancelled its appearances in North Carolina, and speculation has ignited that the former Speaker of the House is preparing to exit the race.

Sources told NewsChannel 36 Gingrich has canceled all of his appearances in North Carolina next week.

Gingrich was scheduled to make multiple appearances throughout the state, including a visit to Lincoln Charter School in Denver next Wednesday. Fourth graders planned to present him with an American history project.
