When Clements was first sworn in in 1979, he became the first Republican to have served as governor of Texas since Reconstruction. When Clements left office for good at the end of his second term in 1991, his eight years in office were the most served by any Texas governor until Rick Perry surpassed his total in 2009. Clements was the first governor to be elected to multiple terms since Texas changed its constitution in 1972 to extend their governor's term of office to four years; since then, Perry and his predecessor, George W. Bush and successor, Greg Abbott, also Republicans, have also won multiple terms.
