<P> In the history of the United States, the House of Representatives has impeached sixteen officials, of whom seven were convicted . (Another, Richard Nixon, resigned after the House Judiciary Committee passed articles of impeachment but before a formal impeachment vote by the full House .) Only two Presidents of the United States have ever been impeached: Andrew Johnson in 1868 and Bill Clinton in 1998 . Both trials ended in acquittal; in Johnson's case, the Senate fell one vote short of the two - thirds majority required for conviction . </P> <P> Under the Twelfth Amendment, the House has the power to elect the President if no presidential candidate receives a majority of votes in the Electoral College . The Twelfth Amendment requires the House to choose from the three candidates with the highest numbers of electoral votes . The Constitution provides that "the votes shall be taken by states, the representation from each state having one vote ." It is rare for no presidential candidate to receive a majority of electoral votes . In the history of the United States, the House has only had to choose a President twice . In 1800, which was before the adoption of the Twelfth Amendment, it elected Thomas Jefferson over Aaron Burr . In 1824, it elected John Quincy Adams over Andrew Jackson and William H. Crawford . If no presidential candidate receives a majority of the electoral votes, the Senate elects the Vice President from the two candidates with the highest numbers of electoral votes . </P> <Table> <Tr> <Th_colspan="2"> Affiliation </Th> <Th> Members </Th> <Th> Delegates / resident commissioner (non-voting) </Th> <Th> State majorities </Th> </Tr> <Tr> <Th> </Th> <Td> Republican Party </Td> <Td> 239 </Td> <Td> </Td> <Td> 32 </Td> </Tr> <Tr> <Th> </Th> <Td> Democratic Party </Td> <Td> 193 </Td> <Td> </Td> <Td> 12 </Td> </Tr> <Tr> <Td> </Td> <Td> Independent </Td> <Td> 0 </Td> <Td> </Td> <Td> 0 </Td> </Tr> <Tr> <Th> </Th> <Td> Vacant </Td> <Td> </Td> <Td> 0 </Td> <Td> </Td> </Tr> <Tr> <Th_colspan="2"> Total </Th> <Th> 435 </Th> <Th> 6 </Th> <Th> </Th> </Tr> </Table> <Tr> <Th_colspan="2"> Affiliation </Th> <Th> Members </Th> <Th> Delegates / resident commissioner (non-voting) </Th> <Th> State majorities </Th> </Tr>
