Here's the poll -- http://www.militarycity.com/polls/
Here's an article about it that was apparently written/published on the Military Times website too, but I'm too lazy to find it on there today... Here it is as a re-post on the TruthOut website -- http://www.truthout.org/docs_2006/123006Y.shtml
Excerpt from article:
The American military - once a staunch supporter of President Bush and the Iraq war - has grown increasingly pessimistic about chances for victory, according to the 2006 Military Times Poll.
For the first time, more troops disapprove of the president's handling of the war than approve of it. Barely one-third of service members approve of the way the president is handling the war.
When the military was feeling most optimistic about the war - in 2004 - 83 percent of poll respondents thought success in Iraq was likely. This year, that number has shrunk to 50 percent.
