In 1968, Buckley challenged liberal Republican Senator
Jacob Javits for re-election. Javits won easily, but Buckley received a large number of votes from disaffected conservative Republicans, and in 1970, ran for the U.S. Senate against liberal Republican incumbent
Charles Goodell. Goodell had been appointed to the Senate by New York Governor
Nelson Rockefeller following the assassination of Senator
Robert F. Kennedy and had made a name for himself in the Senate as an opponent of the
Vietnam War. Buckley's campaign slogan, plastered on billboards statewide, was "Isn't it time we had a Senator?"

With Goodell and the Democratic nominee,
Richard Ottinger, splitting the liberal vote, Buckley won a plurality (38%) and entered the Senate in January 1971.
In 1974, he proposed a "human life" amendment, which defined the term "person" in the Fourteenth Amendment to include the unborn.
In his 1976 re-election bid, with Rockefeller's liberal GOP faction falling apart, Buckley was able to receive the Republican nomination. Initially, he was favored for re-election, because the frontrunner in the crowded Democratic field was
Manhattan Congresswoman
Bella Abzug, a liberal feminist reviled by the right. But when
Daniel Patrick Moynihan, the U.S. Ambassador to the UN, made a late entrance into the Democratic primary and narrowly defeated Abzug, Buckley could no longer count on getting the votes of moderate Democrats. Moynihan went on to defeat Buckley by a wide margin.
After his loss, Buckley moved to Connecticut, and in 1980 received the Republican nomination for the Senate seat being vacated by the retirement of
Abraham Ribicoff. He lost the general election to
Christopher Dodd, who still serves in the Senate.
He was the last Senator to be elected from a party other than the Democrats or Republicans. Since 1974, two independent candidates (
Bernie Sanders of Vermont and
Joe Lieberman of Connecticut) have been elected, but no minor-party candidates have won election to the Senate.
