Question: Can a President be voted out by his own party during his term and another member of that same party be voted in to carry on that term of office?
There are only a few ways that a sitting US president can leave office.
1) Die in office
2) Resign
3) Impeached and removed from office.
Since 1841, over one-third of all American Presidents have either died in office, became disabled, or resigned. However, no American President has ever been forced from office due to impeachment. In fact, only four times in our history, has Congress held serious discussions of impeachment:
• Andrew Johnson was actually impeached when Congress became unhappy with the way he was dealing with some post-Civil War matters, but Johnson was acquitted in the Senate by one vote and remained in office.
• Congress introduced a resolution to impeach John Tyler over state's rights issues, but the resolution failed.
• Congress was debating his impeachment over the Watergate break-in when President Richard Nixon resigned.
• William J. Clinton was impeached by the House on charges of perjury and obstruction of justice in relationship to his affair with White House intern Monica Lewinsky. Clinton was eventually acquitted by the Senate.
