Why is this man smiling?
Arizona Sen. John McCain could understandably be scowling: He could face a more difficult political landscape than any presidential candidate in a generation.
Only 39% of Americans have a favorable view of the Republican Party he represents, the latest USA TODAY/Gallup Poll shows. A record 63% say the Iraq war he defends was a mistake. The disapproval rating for President Bush, the incumbent McCain has embraced, has hit 69%, the most negative assessment of any president since Gallup began asking the question 70 years ago.
