The Republican nominee for Governor will most likely be US Attorney Christopher J. Christie. There is considerable talk in Trenton that Governor Corzine will not seek re-election. In that case, the Democratic nominee will be Senate President Dick Codey... who without any doubt whatsoever would finally win the Governorship in his own name after serving as Acting Governor for three extended periods in the past two terms.
It will also be interesting to see if the NJ/VA/US President trend continues... for the past twenty years, when the nation elects a Democrat president, both states elect a Republican governor and vice versa.
I was going to quote Phil and say John Murphy, which I believe, and ask why you think that it will be a Christie/Codey matchup. I always thought Christie wanted to be senator rather than governor but passed in 2008 and will try for Menendez in 2012. And why, even if Corzine did not run again, would the Democrats pick Codey who they booted for Corzine, and why would Codey accept? However, I still think it will a Murphy v. Andrews matchup with Murphy winning something like 49-47
