But the CNN/Opinion Research Corporation survey released Wednesday indicated that support for closing the detention facility has increased dramatically since 2005.
Fifty-one percent of those questioned in the survey support the closing of prison at Guantanamo Bay, with 47 percent against the closing. That's basically a split, when taking into account the survey's sampling error of plus or minus 3 percentage points.
But the 51 percent who support the closing of the facility is a 15 point increase from 2005, when 36 percent polled backed the shutting down of prison at Guantanamo Bay. The 47 percent who are against the closing is down 11 points from 2005, when 58 percent opposed closing the facility.
The poll's release comes as CNN has learned that President Obama is planning to issue three executive orders on Thursday that would show a clean break from the Bush administration on the war on terror, including one demanding that the U.S. military prison at Guantanamo Bay be closed within one year, according to a senior administration official and a congressional aide.
Since 2001, the U.S. has held foreign terrorist suspects at the detention facility. The prison became a lightning rod for critics who charged that the Bush administration had used torture on terror detainees. Former President Bush and other senior officials repeatedly denied that the U.S. government had used torture to coax intelligence out of terror suspects.
