This is way too big of a propaganda offensive just to bolster the senate democrat efforts to pass useless resolutions against the Surge. This must be flanking an effort to pull out of Iraq entirely so I'd be looking for Hillary to sudden announce that she has concluded that 'there is no choice' but to withdraw immediately 'because of the faulty intelligence and disasterous lack of leadership'. Lets see if it takes more or less than a week for this to occur.
I'd give it 2-4 weeks. They don't really work that hard in congress.
