Americans Opposed To Closing Guantanamo

According to a Gallup survey, many Americans don't want to close Gitmo or transfer it's "guests" to U.S. prisons. The meat:
Americans remain opposed to closing the Guantanamo Bay prison in Cuba and moving some of the terrorist suspects being held there to U.S. prisons: 30% favor such actions, while 64% do not. These attitudes could present a significant roadblock for President Obama at a time when he seeks congressional approval to move terrorist suspects from Guantanamo to a converted state prison in northwestern Illinois.

President Obama signed an executive order after his inauguration that called for the closing of Guantanamo, and he recently reiterated his commitment to doing this in his West Point speech on Afghanistan. The plans announced this week represent the first concrete effort to follow through on his promise, but occur in the context of continuing opposition from the American public. About two-thirds of Americans in the Nov. 20-22 poll oppose such a move, virtually the same as measured last May.
I'm not really surprised by the continued opposition to this idea. What seems odd to me is that there has been no real change in that opposition since earlier this year. One would think that public opinion might shift one way or the other in a seven-to-eight month time span.
