NEWARK, N.J. — With his election to the U.S. Senate, Newark Mayor Cory Booker faces the question of how he will translate to Washington his celebrity status, frequent travel and penchant for replying on Twitter to low-level requests from constituents.

Booker, who beat Republican Steve Lonegan in a special election Tuesday, is moving from the top of the executive branch, albeit at a local level, to being one of 100 senators. That means he has to get used to shaping coalitions rather than being the boss, New Jersey’s other senator, Robert Menendez, said in an interview.
