Switching to the Democratic side, Clinton is still the favorite among self-identified Democratic primary voters. She receives 51 percent while Vermont Sen. Bernie Sanders comes in at 22 percent. Yet that is Clinton’s worst showing -- and Sanders’ best. Support for Clinton was 59 percent two weeks ago, 61 percent a month ago -- and has been as high as 63 percent in the months since Sanders entered the race. Vice President Joe Biden, who is said to be considering a run, sits at 13 percent support.

The economy is the top concern for both Democrats and Republicans. Health care comes in second for Democrats, while for Republicans it is terrorism.

Voters split on the job Barack Obama is doing as president: 46 percent approve and 46 percent disapprove. Two weeks ago it was 47-48%.  A year ago, 42 percent of voters approved and 49 percent disapproved (August 2014).
