Question: In which election did Norm Coleman won to become the last republican elected as of 2017?

Context:
George W. Murray
George Washington Murray (September 22, 1853 – April 21, 1926), born into slavery in South Carolina, became educated and worked as a teacher, farmer and politician.
 After serving as chairman of the Sumter County Republican Party, he was elected in the 1890s as a United States congressman from South Carolina.
 He was the only black member in the 53rd and 54th Congresses.
 Because South Carolina passed a constitution in 1895 that effectively disenfranchised blacks and crippled the Republican Party, Murray was the last Republican elected in the state for nearly 100 years.
 The next Republican, elected in 1980, was the result of a realignment of voters and parties; he was white.

 In 1994, Pataki ran for governor against three-term incumbent Mario Cuomo, defeating him by over a three-point margin as part of the Republican Revolution of 1994.
 Pataki, succeeding a three-term governor, would himself be elected to three consecutive terms, and was the third Republican Governor of New York elected since 1923, the other two being Thomas Dewey and Nelson Rockefeller.
 Pataki, as of January 2017 is the last Republican to serve as Governor of New York.
