The Zogby poll describes the Palin Effect on the ticket:
"Clearly, Palin is helping the McCain ticket. She has high favorability numbers, and has unified the Republican Party. The striking thing here in this poll is that McCain has pulled ahead among Catholics by double-digits. On the other hand, Palin is not helping with likely voting women who are not aligned with either political party. The undecided independent women voters decreased this week from 15% to 7%, but those women went to Obama. Palin is also helping among men, conservatives, notably with suburban and rural voters, and with frequent Wal-Mart shoppers, who tend to be "values" voters who like a good value for their money."
These results are based on Sept. 4-6 interviewing, and include two full days of polling after the conclusion of the Republican National Convention last Thursday night. McCain has outpolled Obama on both Friday and Saturday, and is receiving a convention bounce just as Obama did last week.
