If you were told a Republican has a 30-point lead in one of the two states that hold off-year gubernatorial elections, in the past you would have guessed Virginia, seat of the old confederacy, certainly not New Jersey. But the politics have flipped. Republican Chris Christie is cruising to victory in the blue state of New Jersey, and Democrat Terry McAuliffe has a big lead in Virginia, topping a ticket that could sweep enough Democrats into elective office to install a Democratic attorney general for the first time in decades and break the GOP’s lock on the Virginia General Assembly.
