A HuffPost/YouGov poll asked: “All in all, considering the costs to the United States versus the benefits to the United States, do you think the war with Iraq was worth fighting, or not?” The response:
Only 24 percent of respondents to the new poll said they thought the war had been worth fighting, while 54 percent said it had not been. Another 22 percent said they were not sure. Three-quarters of Democrats and 55 percent of independents said the Iraq War was not worth fighting. But Republicans were more likely to say that it was worth the cost than it was not — by a 47 to 30 percent margin.

...found that 53% of Americans think the war was a mistake and 42% percent do not. Kevin Drum's reaction:
How is it, ten years after the fact and with the benefit of hindsight, that 42 percent of the country still believes that invading Iraq wasn’t a mistake? What would it take to convince these people?
