Obama is enjoying his post-nomination-win surge in most polls. But every once in a while, you encounter something interesting, and ominous for the Democratic nominee.

Fox News/Opinion Dynamics:

In the generic ballot, voters prefer a Democratic president to a Republican 42-35. But in Obama-McCain matchup, with Nader and Barr offered as possibilities, Obama leads, 42-39. Take out the third-party possibilities and Obama leads, 45-41.

Liberals will laugh at or decry the question, but they asked, ‘How much do you think Obama loves America?” The partisan breakdown was about what you would expect. But among independents, 45 percent said, “a great deal,” 23 percent said “somewhat,” 10 percent said, “not much” 9 percent said “not at all,” and 13 percent said they didn’t know. For McCain, 66 percent of independents said “a great deal,” 17 percent said “somewhat,” 2 percent said “not much,” 5 percent said “not at all,” and 10 percent said they didn’t know.

Asked about preference for first lady (I know, odd question) the partisan breakdown was again predictable, but among independents, Cindy McCain led, 38 percent to 24 percent.

Fox/Opinion Dynamics asked, “If the United States were hit with another terrorist attack, would you feel more comfortable with Barack Obama or John McCain as president?” McCain led 50-33 overall; among Democrats, Obama led 62-20; among Republicans, McCain led 87 to 7; and among independents, McCain led, 50 percent to 19 percent.

Finally, they asked, “Barack Obama has distanced himself from his former pastor Jeremiah Wright because of the controversial and unpatriotic comments Wright made. How much does it trouble you that Barack Obama attended Rev. Jeremiah Wright’s church and listened to Wright’s comments for 20 years?”

Overall, it was 53 percent troubled (29 percent a great deal), 44 percent not troubled (31 percent not at all).

Among Independents, 57 percent said they were troubled, (25 percent a great deal), 42 percnet said the weren’t troubled (33 percent not at all).
