Harry S. Truman

==== Approval rating falls; Republicans win Congress in 1946====
The president's approval rating dropped from 82&nbsp;percent in the polls in January 1946 to 52&nbsp;percent by June.{{sfn|McCoy|1984|pp=64–65}} This dissatisfaction led to large Democratic losses in the 1946 midterm elections, and Republicans took control of Congress for the first time since 1930. When Truman dropped to 32&nbsp;percent in the polls, Democratic Arkansas Senator [[William Fulbright]] suggested that Truman resign; the president said he did not care what Senator "Halfbright" said.{{sfn|Dallek|2008|pp=48–50}}{{sfn|McCoy|1984|p=91}}

Truman cooperated closely with the Republican leaders on foreign policy but fought them bitterly on domestic issues. The power of the labor unions was significantly curtailed by the [[Taft–Hartley Act]] which was enacted [[veto override|over Truman's veto]]. Truman twice vetoed bills to lower income tax rates in 1947. Although the initial vetoes were sustained, Congress overrode his veto of a tax cut bill in 1948. In one notable instance of bipartisanship, Congress passed the [[Presidential Succession Act of 1947]], which replaced the secretary of state with the Speaker of the House and the president pro tempore of the Senate as successor to the president after the vice president.{{sfn|McCoy|1984|pp=96–102}}
