CNN poll: Obama leads in swing states


A new USA Today/Gallup poll finds President Obama holds a small advantage over Mitt Romney, 47% to 45%, in 12 key states. It’s the same margin found in a May poll.

When zooming out to include voters from the other states, the gap expands to a four-point margin in favor of Obama, 48% to 44%.

Meanwhile, a new Investors Business Daily/Christian Science Monitor poll shows Obama leading nationally by just one point, 43% to 43%.
