Christie is very popular with republicans and independents.. but corzine was able to carry 45% of the vote in a very bad year for the democrats and with huge levels of unpopularity.. so I think the election could be very close in 2013. and with a strong candidate like Booker, probably christie would prefer not to be a candidate for reelection.
Cory Booker is a friend and ally of Chris Christie, and they have appeared in numerous interviews together. Booker isn't running unless Christie decides to step aside for him.
It's interesting the two are close considering their political differences.
