Houston ? Former Senator and Treasury Secretary Lloyd Bentsen, the courtly Texan who famously put down vice presidential rival Dan Quayle in a 1988 debate by telling him “you’re no Jack Kennedy,” died Tuesday. He was 85.

Bentsen, who represented the state in Congress for 28 years, died at his Houston home, his family said. He had been under a doctor’s care since a pair of strokes in 1998.

Bentsen’s political career took him from a county judgeship in the Rio Grande Valley in the 1940s to six years in the U.S. House, 22 years in the Senate and two years as President Clinton’s first treasury secretary.

A shrewd legislative operator, he maneuvered with ease in Democratic and Republican circles alike on Capitol Hill, displaying expertise on tax, trade and economic issues as well as foreign affairs.

“The state of Texas has had great senators, but no senator has ever been a better senator than Lloyd Bentsen,” Senate Minority Leader Harry Reid, D-Nev., said Tuesday on the Senate floor.

Republican Texas Gov. Rick Perry ordered flags at state buildings flown at half-staff for five days.

“Today we mourn the loss of a war hero and true Texas leader who earned the respect of the nation with his dedication to public service,” Perry said in a statement.

President Bush said in a statement that he and his family were saddened by Bentsen’s death.

“During his time in Congress, he was known for his integrity and for seeking bipartisan solutions,” the president said. “Lloyd Bentsen was a man of great honor and distinction.”

In 1988, Democratic presidential nominee Michael Dukakis tapped Bentsen as his running mate while the GOP nominee, Vice President George Bush, chose Sen. Dan Quayle of Indiana.

In their Oct. 5, 1988, vice presidential debate, Quayle said: “I have as much experience in the Congress as Jack Kennedy did when he sought the presidency.”

Quayle had made similar comments before and Bentsen was prepared.

“Senator, I served with Jack Kennedy,” Bentsen said. “I knew Jack Kennedy. Jack Kennedy was a friend of mine. Senator, you’re no Jack Kennedy.”

The Dukakis-Bentsen ticket lost 40 states – including Texas – to the Bush-Quayle team.

“I have lost a valued friend and wonderful running mate. The nation has lost a great public servant,” Dukakis said Tuesday.

Despite his stately reserve, Bentsen liked to recall a youth of derring-do. He recalled that when he was in Army flight training during World War II, he took a plane too far into a dive and barely avoided a crash. He thought he had gotten away with it until the trainer found corn cobs stuck to the plane.

He later flew 50 bomber missions over Europe.
