Only 15 or 42 US presidents have won at least two consecutive terms. This gives about 36%. About 70 percent of those who have served as president since 1825 (or 26 of 37 men) failed to win the election for two consecutive terms. This is either because they died, didn't run again, or lost their party or national election. In the US, of the 42 presidents before Obama, only 15 won reelection. 12 didn't run again (because of death, etc.), 18 lost in either their bid for party nomination or in a national election.
Historically, about 70% of incumbent U.S. presidents who seek reelection have been successful. This percentage varies depending on the political context and specific elections, but generally, incumbents have a significant advantage due to their established presence and resources. Notably, some presidents, such as Jimmy Carter and George H.W. Bush, lost their bids for reelection despite being incumbents.
