Hillary Clinton has a 55 percent to 36 percent lead in Pennsylvania, according to a SurveyUSA poll conducted March 8-10. The margin of error is 4 percent. This finding is roughly comparable to recent polls by Rasmussen Reports and American Research Group.

In somewhat of a departure from other states, Clinton leads Obama among men 47 percent to 42 percent while enjoying her customary big lead among women, 62 percent to 32 percent. She also leads in all age groups, including younger voters. She has a 61 percent to 29 percent lead among white voters who make up 80 percent of the sample while Obama leads 76 percent to 22 percent among black voters who make up 15 percent of the sample. There is not a big Hispanic vote.

The economy is named by 43 percent of voters as the top issue and Clinton leads on this one by 60 percent to 34 percent. Health care comes next, cited by 20 percent of voters, and Clinton leads 63 percent to 31 percent. The only other issue is double-digits was Iraq, named by 16 percent of voters, and Clinton had a within-the-margin of error lead of 48 percent to 45 percent.
