Let's just be honest. Democrats never liked the War on Terror. They never really supported it. There were a lot of reasons for this. Some were partisan - they just didn't want to support anything George W. Bush wanted to do. Some were ideological - they really didn't believe we had the right to pursue our enemies, and they just plain didn't want to because they don't like when the U.S. uses force aggressively. Some were strategic - if they backed the idea that we should be doing this sort of thing, they gave tacit approval to the use of funds they would prefer to spend on more Democrat-friendly priorities.
