Gov. Chris Christie’s popularity is up, while President Barack Obama’s is down. The new data from Fairleigh Dickinson University’s PublicMind poll says that almost two-thirds approve of the job done by the governor, but only 45 percent in the state approve of Obama’s job. These show a positive change for Christie, but is down for Obama. The poll notes that Christie’s popularity crosses party, but Obama doesn’t cross the aisle well in his support.
