There are also eight counties that had a perfect record for the ten elections between 1960 and 1996. One, Ferry County, Washington, is a semi-bellwether. In 1988, it had a tie down to the very vote between Dukakis and Bush.
In 2000, the streaks were ruined for the state of Delaware, as well as New Castle County, Del., and Socorro County, N.M. All of the other bellwethers remain so.
The state results in 2000 for the bellwether states were:
Delaware - Kerry +13.1
Missouri - Bush +3.3
The bellwether county results were:
New Castle, DE - Gore +23.0
Socorro, NM - Gore +1.8
Vigo, IN - Bush +1.2
Van Buren, AR - Bush +4.1
Lincoln, MO - Bush +10.0
Logan, AR - Bush +14.8
Eddy, NM - Bush +18.1
Ferry, WA - Bush +31.7
Of course, you could argue that since these (those for the counties) are Popular vote results and Bush did not win the popular vote, New Castle and Socorro are the counties with the longest streak as bellwethers.
