Democrats and historic New Deal policies. Roosevelt's election in 1932 marked a shift in government power towards the executive branch. Numerous New Deal initiatives came from the White House rather initiated by Congress. President Roosevelt pushed his agenda in Congress by detailing Executive Branch staff to friendly Senate committees (a practice that ended with the Legislative Reorganization Act of 1946). The Democratic Party controlled both houses of Congress for many years. During this time, Republicans and conservative southern Democrats formed the Conservative Coalition. Democrats maintained control of Congress during World War II. Congress struggled with efficiency in the postwar era partly by reducing the number of standing Congressional committees. Southern Democrats became a powerful force in many influential committees although political power alternated between Republicans and Democrats during these years. More complex issues required greater specialization and expertise, such as space flight and atomic energy policy. Senator Joseph McCarthy exploited the fear of communism during the Second Red Scare and conducted televised hearings. In 1960, Democratic candidate John F. Kennedy narrowly won the presidency and power shifted again to the Democrats who dominated both houses of Congress until 1994. Since 1970: Contemporary Era Congress enacted Johnson's Great Society program to fight poverty and hunger. The Watergate Scandal had a powerful effect of waking up a somewhat dormant Congress which investigated presidential wrongdoing and coverups; the scandal "substantially reshaped" relations between the branches of government, suggested political scientist Bruce J. Schulman. Partisanship returned, particularly after 1994; one analyst attributes partisan infighting to slim Congressional majorities which discouraged friendly social gatherings in meeting rooms such as the Board of Education. Congress began reasserting its authority. Lobbying became a big factor despite the 1971 Federal Election Campaign Act. Political action committees or PACs could make substantive donations to Congressional candidates via such means as soft money contributions. While soft money funds were not given to specific campaigns for candidates, the money often benefited candidates substantially in an indirect way and helped reelect candidates. Reforms such as the 2002 Bipartisan Campaign Reform Act limited campaign donations but did not limit soft money contributions. One source suggests post-Watergate laws amended in 1974 meant to reduce the "influence of wealthy contributors and end payoffs" instead "legitimized PACs" since they "enabled individuals to band together in support of candidates". From 1974 to 1984, PACs grew from 608 to 3,803 and donations leaped from $12.5million to $120million along
