Most Impressive statewide landslides

[Vazdul (Formerly Chairman of the Communist Party of Ontario)]

Democratic Governor Cecil Andrus won by a 2 to 1 margin, winning all but two counties. In Idaho.

His Republican opponent ran on a platform of Universal Health Care. In Idaho. In 1990.

Here's another good one.

Bear in mind that in this election, Schaefer was not an incumbent seeking reelection-- it was an open seat, and the Democrats had held the Governorship since 1969. Schaefer carried every county in the state, including uber-Republican Garrett County, with over 60% of the vote, and received 82% of the vote statewide.

I've always considered Tom Kean's 1985 landslide victory to be the one against which all other are measured. He won 71% to 24%, carrying virtually every town in New Jersey, including Newark, Camden, and Jersey City. His margin of victory was so large, in fact, that he swept in 4 Republican Assemblymen in heavily Democratic, heavily urban Hudson County (Jersey City, Union City, Hoboken).

Yeah Kean won 60% of the urban vote in that Election. It would be impossible for a Republican to win a state or a US House Seat in Hudson County nowadays. Kean's Governor's Race  in 1981 against Jim Florio was close though. I would like to see a map of the 1981 Race but thats not on this site.

Here, I made one myself using the data from this site.
