One thing that I notice about these numbers is that only one candidate seems to be taking votes away from Obama, Romney.
Another thing I notice is that Palin seems to be awarding votes to Obama
President Barack Obama tops all leading GOP White House hopefuls, hitting the all- important 50-percent mark against every candidate but Romney:
47 - 41 percent over Romney, unchanged from June 8;
50 - 38 percent over Bachmann, who was not matched against Obama June 8;
53 - 34 percent over Sarah Palin, compared to 53 - 36 percent June 8;
50 - 37 percent over Perry, who was not matched against Obama June 8.
