Pew surveys Americans on whether or not the U.S. is "winning the war on terrorism."
The overall opinion hasn't changed very much, but internally, Republicans and Democrats have flipped significantly on the question, with more Democrats believing the U.S. was losing when Bush was president, and 22 percent of Republicans flipping on the question now that Obama is in office. Presumably, it's because someone might build an Islamic community center a few blocks away from Ground Zero.
What's really odd about this is, in terms of al-Qaeda's ability to carry out a large-scale attack, they're unquestionably losing. They're reduced to bragging about attacks that didn't work and didn't kill anyone, and begging their ideological supporters on the Internet to go out and carry out attacks on their own because they struggle with the logistics of actually recruiting and training operatives well enough to facilitate them. The world's Muslims, for the most part, hate them. As Peter Bergen writes, al-Qaeda's "assets are few, and shrinking."
How much of its own soul America is losing in the process is a different question, but I'm pretty sure it's not the one the respondents were answering.
