George W Bush 2001-2005. We know the war on terror still happened and since he wasn't president in 2008, it's clear in the gta universe he only served one term.​

Joseph Lawton 2005-2013. We're not told much about him, besides him being the president during gta 4 and 5 so likely served two consecutive terms.

Sue Murry 2013-2017. I believe Jock Cranley won the governor race in San Andreas (due to gerrymandering) and so Murry instead ran for president.

Donald Cleethorpe 2017-present. We know he has a tower in Liberty City called Cleethorpe towers. He lost the election to Sue Murry in 2020, however I think in the gta universe the J6 insurrection was successful and is currently in his third term.
