But battleground voters were evenly split on President Obama, with a statically even 48 percent approving of how he handles his job and 49 percent disapproving.

And the survey found that a majority of voters (52 percent) do not support the president's signature healthcare law, while nearly as many disapprove of the Supreme Court's decision to uphold that legislation. In battleground states, a full 50 percent say the "law was a bad idea from the start, and it's still a bad idea," and a plurality agree that the law should be repealed.

Still, 53 percent say they support Democrats who argue that we shouldn't "go back and refight the same old healthcare political battles."

The survey polled voters in Colorado, Florida, Iowa, Michigan, Nevada, New Hampshire, New Mexico, North Carolina, Ohio, Pennsylvania, Virginia and Wisconsin.
