Chris Christie officially dropped out of the presidential race Wednesday after repeated calls from New Hampshire’s governor, Chris Sununu, and other Nikki Haley supporters to do so — but will this help Ms. Haley’s campaign?

News that Mr. Christie would be suspending his presidential campaign at a town hall in Windham, New Hampshire leaked shortly before the event. The move was somewhat expected — Mr. Christie had not campaigned much outside New Hampshire, where he was polling in a distant third place — but the timing caught many close to the Christie campaign by surprise.
