Look the right-wing can try and put together all the bs polls they want to try and make the Iraq war look less unpopular than it actually is.
But we just had an election where the GOP took it on the chin. That is proof positive that not only is war unpopular, but that unpopularity is having a drastic impact on the electoral fortunes of the President's political party. Every cycle we have a bunch of polls that say a lot of stuff and then the election tells us what is really going on. And what's really going on is that Iraq is killing the GOP.
So if we remain in Iraq and condition do not improve, the GOP is going to be crushed in 2008. You don't need polls to determine that result. Just look at how people actually voted.
