New Jersey just moved up their primary to February 5th, according to the Philly Inquirer:
So the Senate yesterday voted 33-5 to move the 2008 primary date up a few more weeks to Feb. 5, putting it after only the Iowa and Nevada caucuses and the New Hampshire and South Carolina primaries. At least six other states also plan to hold primaries that day.
Feb. 5 is the first date at which states besides New Hampshire and South Carolina can hold primaries. Utah, Arizona, New Mexico, Alabama, Arkansas and North Carolina are among states planning to hold primaries that day.
This is almost certainly a Democrat/Clinton pushed operation. Her Obama strategy is almost certainly to move up big states. It may have a residual impact on the GOP side. This may help Giuliani.
