George P. Bush

AUSTIN, Texas — George P. Bush on Monday formally announced he is seeking re-election as Texas land commissioner next year, hoping to continue running a little-known but powerful agency in a state where his political-dynasty family has been prominent for decades.

Bush’s grandfather, President George H.W. Bush, was once a Texas congressman and his uncle, George W. Bush, won two Texas gubernatorial elections before leaving for the White House.

George P. Bush, 41, grew up in Florida, where his father, Jeb, was governor and launched his unsuccessful presidential campaign last year. The younger Bush won the position of Texas’ land commissioner handily in 2014, becoming the first in his family to win his first election.

After his father bowed out of the 2016 presidential race, Bush campaigned for Donald Trump as chairman of the Texas Republican Party’s victory committee — even though his family shunned the eventual president.
