In 1942, following his appointment to the National War Labor Board, Hawkes ran for United States Senate. He defeated
Gill Robb Wilson in the Republican primary and Democratic incumbent
William H. Smathers in the general election. As Senator, Hawkes was an ardent conservative, particularly on economic issues. Early in Hawkes's term,
Senate Minority Leader Charles L. McNary remarked of him, "His economic thinking goes back to
B.C." Hawkes supported the wartime measures taken by the Roosevelt administration but was a consistent advocate for a return to "free enterprise" policies once the war ended. In particular, critics pointed to a recent fundraising dinner speech in which Hawkes said, "I have never hated anyone in my life longer than overnight. There is one exceptionand he [Franklin D. Roosevelt] lies buried in
Hyde Park" as a fatal political blunder. Hawkes responded sharply to the calls for his withdrawal,"This choice has been made by whipping recalcitrant supporters into line and by utilizing other pressures of power politicsin short, by substituting one-man control for the right of the people to choose their own candidate. We are being treated to the emergence of a Republican oligarchy in New Jersey in which the titular head of the party becomes the state, not the representative of the people in the state."Soon, it became clear that Van Alstyne would fail to unify the party establishment in opposition to Hawkes. On February 13, state treasurer
Robert C. Hendrickson announced his campaign for the seat, bringing the endorsements of 17 out of 21 county Republican leaders. Only
Bergen County endorsed another candidate, state labor commissioner and native son
Harry Harper.
Atlantic,
Ocean, and
Cape May counties remained neutral. Hawkes had no institutional support, but reiterated that he would remain in the race. Hawkes ended his campaign on March 5, 1948, denouncing "Boss Driscoll" and other party leaders as "New Deal Republicans". Hendrickson went on to win the nomination and general election.
1952 Republican National Convention At the
1952 Republican National Convention, Hawkes supported his former colleague, Senator
Robert A. Taft of
Ohio, for the presidential nomination over General
Dwight D. Eisenhower. He continued to speak out for a more conservative Republican position. == Personal life and death ==
