CHICAGO: After more than a month in a Texas hospital battling bronchitis, former US president George H.W. Bush has taken a turn for the worse and is in intensive care with a “stubborn fever,” a spokesman said on Wednesday (Thursday in Manila).

“He’s had a series of setbacks now that have landed him in guarded condition in the intensive care unit,” where he was transferred on Sunday, spokesman Jim McGrath said.

“Early last week it was really looking good, but then it seemed a couple of dominoes started falling and it was taking us in the wrong direction.”

The 88-year-old was first admitted to Methodist Hospital in Houston on November 7 for bronchitis treatment and released on November 19. But he was readmitted four days later after his cough flared up again.

Doctors had initially hoped to have the elder statesman home for Christmas, but he was instead forced to spend the holiday in the hospital, where he was joined by his wife Barbara, son Neil and grandson Pierce.

“His family was with him, and he’s conscious and he’s able to engage in humorous banter with his doctor,” McGrath said

McGrath later said that doctors were “cautiously optimistic” but that there was no talk yet of a discharge date.

Bush, a Republican, served just a single term in the White House from 1989 to 1993, despite sending US troops to victory in Iraq in the first Gulf War, expelling Saddam Hussein’s forces from Kuwait.

He was seen as a moderate, low-key president compared to the showmen Ronald Reagan, who preceded him and Bill Clinton, who followed, but respect for his hard-edged realism in foreign policy has grown since his electoral defeat.

Domestically, he suffered a loss of support among his own conservative base after being forced to abandon his campaign vow: “Read my lips. No new taxes.”

The decorated World War II veteran served in a number of top government posts, including as vice president, director of the Central Intelligence Agency and US ambassador to the United Nations.

Although he was dogged by a reputation as a wimp and his standing suffered in difficult economic times for the United States, he heads an impressive political dynasty that may yet have a future in high office.

His son, George Bush, served two terms as president and also went to war with Iraq, this time sending US-led troops all the way to Baghdad to overthrow Saddam, whom he had wrongly accused of hoarding weapons of mass destruction.

The younger Bush’s term ended in 2008 on a low note with the economy in deep crisis, tens of thousands of US troops still fighting in Iraq and the author of the 9/11 attacks, Osama Bin Laden, still at large.

But George H.W. Bush’s older son, former Florida governor Jeb Bush, is still seen as an influential player within the Republican Party and may one day launch a presidential bid of his own.
