Christie Steps Up Attacks on Rubio

Gov. Chris Christie, “smarting from weeks of negative commercials against him in New Hampshire, has struck back at several Republican opponents in animated appearances on the campaign trail this week,” the New York Times reports.

“One rival has drawn especially biting attacks: Senator Marco Rubio of Florida. Mr. Christie has long criticized Mr. Rubio for lacking executive experience. But in recent days he has dialed up his attacks, repeatedly deriding Mr. Rubio as a political lightweight in a tone that verges on contempt.”
