Well of the course they do; the Republicans' resolutions are desperate measures that wouldn't allow effective opposition to the surge. The Democrats are the majority, and have been elected to either significantly change the course in this war, or end it. They don't have to put up with this weak shuffling from the congressional opposition : "change the course but support the surge" is worthless, and is simply meant to buy time. Although the Democrats's non-binding resolution won't get much achieved either, it's still noticeably better. The Republicans are going to have to compromise further, they're in a position of weakness after all.
