John McCain fears Americans may turn against Iraq war, while polls show 62% of Americans already have turned

What world does John McCain live in? He's worried that Americans "may" turn against the Iraq war? From AP:

"By the way, a lot of us are also very concerned about the possibility of a, quote, 'Tet Offensive.' You know, some large-scale tact that could then switch American public opinion the way that the Tet Offensive did," the Arizona senator said.

Last month, an Associated Press-Ipsos poll found that 62 percent said the United States made a mistake in going to war in Iraq.
