The first national poll conducted entirely after Barack Obama returned from his foreign tour suggests that it did not give him much of a bump.
The CNN/Opinion Research Corp. survey released this afternoon gives Democrat Obama a 51 percent to 44 percent lead over Republican John McCain among registered voters -- about the same margin as Obama's 50 percent to 45 percent edge a month ago.
Of those surveyed, 38 percent said they were certain they will vote for Obama in November, while 33 percent said they were sure about supporting McCain.
With Libertarian Bob Barr and independent Ralph Nader in the mix, the race is closer. Obama leads McCain 46 percent to 42, with Nader at 6 percent and Barr at 3 percent.
Among other findings, the poll found that voters were more confident in how McCain would handle foreign policy issues such as the Iraq and Afghanistan wars, and thought that Obama would better handle domestic issues including the economy and healthcare.
Also, 39 percent said the media coverage of Obama had been too positive, compared to 12 percent who believed that of the coverage of McCain.
And only 22 percent said they thought Obama was attacking McCain unfairly, but 40 percent said they believed McCain was attacking Obama unfairly.
The poll was done July 27-29 and has a margin of error of plus or minus 3 percentage points.
