Rasmussen reports:

Nearly half of U.S. voters (49%) say the United States should not close the terrorist prison camp at Guantanamo Naval Base in Cuba.... Only 32% of voters say the Guantanamo prison camp should be closed, according to a new Rasmussen Reports national telephone survey. One-out-of-five (19%) are undecided. The new findings mark a drop in support for the special prison camp for terrorists where the United States detains about 250 inmates. In a survey in late July, 59% said Guantanamo should be kept open, while 26% said it should be closed.

I don't know why support for keeping the prison open dropped since July, but I imagine support would be a lot higher if more people read Thomas Joscelyn's excellent article on the terrorists at Guantanamo, "Clear and Present Danger", in this week's issue of THE WEEKLY STANDARD.
