THE NUMBERS
      Barack Obama, 51 percent
      John McCain, 44 percent

      This survey, taken after Obama’s high-profile trip to Iraq, Afghanistan, the Middle East and Europe, shows him with about the same lead he had last month. It also shows little change since the spring in the faith people have in Obama to handle the Iraq war, terrorism and other issues. People thought his trip was appropriate by a two-to-one margin. More than four in 10 say they think Obama is acting like he’s already won the election, and nearly that many say McCain is attacking him unfairly. Just over a third think both are arrogant. Obama leads McCain by 46 percent to 42 percent when third-party candidates are included, with Ralph Nader getting 6 percent and Bob Barr, a former GOP congressman from Georgia running for president as a Libertarian, getting 3 percent.

      The CNN-Opinion Research Corp. poll was conducted from July 27-29. It included telephone interviews with 914 registered voters and had a margin of sampling error of plus or minus 3 percentage points.
