Christie recently announced his intention to run for reelection in 2013. Several other Democrats also have expressed interest in running against the Republican, but Booker is widely viewed as the most formidable potential challenger, a sentiment reflected in recent polling. Christie's popularity, meanwhile, has skyrocketed following his response to Hurricane Sandy, recent polling shows.
Booker said he also is looking at a 2014 Senate run. "I am actually looking at that a lot as well," he said.
Sen. Frank Lautenberg (D) will be up for reelection in 2014, but might opt to retire. A recent survey from Democratic automated pollster PPP showed that by a nearly 3-1 margin, Democrats said they prefer Booker to be the 2014 Senate nominee over Lautenberg.
Booker said his decision will be guided by where he thinks he can best make a difference.
"I am absolutely considering running for governor, as well as giving other options some consideration. I am going to be focused on that for the next week to 10 days or so and really come up with a decision that answers my basic question ... where do I believe I can make the best difference for the city I love, for the state I love and the nation I pledge my life to," he said.
