On election day, Clinton won 43% of the popular vote and a wide majority in the Electoral College. Bush won 37.4% of the popular vote, while Perot took 18.9%, the strongest showing by a third party or independent presidential candidate since the 1912 election. Later studies showed that Perot drew his voters roughly equally from Clinton and Bush. Clinton's victory included a sweep of the Northeastern United States, and he also won several states in the Midwest, the West, and the South. By far voters' disappointment with the economy was the major favor in voting against the incumbent, with abortion a lesser factor. In the concurrent congressional elections, Democrats retained control of both houses of Congress.
