Just for the record, Christie did a radio interview this morning and, calling himself a North Jersey Fan, came out for the Yankees.
The other two have not spoken yet, but I’ll bet Corzine comes out for both.

@The Rabbit
There’s an interesting audio about the NJ dividing line between Yankees and Phillies.
I’m no good at links, it’s on WCBS880.com under audio.

The Rabbit, Monmouth County is typically red, mostly for economic reasons.  I think Ocean County is too, but given the southern half of it, perhaps not for the same reason…

@Kevin Are you talking politics or Phillies colors?
If it’s politics-The secession issue that I was addressing had nothing to do either political party.  Southern New Jersey residents, living in the part of the State with fewer counties and a much smaller population (and therefore fewer State Representatives) felt that their tax dollars were not proportionately being returned to the southern part of the State. I’ll spare you all of the details of the debates.
This issue was memorable because at the time I was holding elected public office in South Jersey and was the only aide to the Senator who was Chairman of the State Appropriations Committee. (BTW…This Senator was convicted and sentenced for conspiring to plant drugs on another member of the State Legislature. That might help you with the time frame.) 
The last secession ballot question that I remember was in the late 70’s-early 80’s. (After the first casino opened in Atlantic City.)

Bloomberg, last I recall, was a Red Sox fan.  So he’s clearly pandering.  At least with Rudy, it was genuine, though annoying.

I much prefer Ed Koch on this count.  He would show up as needed when the Yanks or Mets won, but for the most part refused to have much to do with sports.  And he even told the Giants to have their victory parade somewhere else, since they didn’t play in New York anymore.  Compare that with Bloomberg insisting on a parade after the last Giants Super Bowl win.
