A president can only be elected to at most two four-years terms. Further some of them die in office or resign and do not complete their terms,
There was only president in office during the years 1996 and 1997 - William Jefferson "Bill" Clinton.
Of the four assassinated Presidents, only John F. Kennedy was a Democrat. Abraham Lincoln, James A. Garfield, and William McKinley were Republicans.
Actually, all U.S. presidents serve a four-year term (the only exception would be if they died before their term ended, or if they were removed for some crime). A president who has served one term can run for office again and perhaps get re-elected. Barack Obama served his first four years-- he was elected in 2008. Then, he ran for re-election in 2012 and won. So he is serving two terms, eight years total. But perhaps you are asking whether there are presidents who only served four years. Yes, there have been some presidents who ran for re-election and lost-- to cite two examples, Jimmy Carter and George H.W. Bush only served one term of four years.
US presidents are elected to a four-year term. The maximum number of full terms that a president can serve is two. Presidents who took over for another president and have served more than two years can seek only one additional term.
