The five major candidates in the Democratic mayoral primary made one last lap around the city today, with four of them hoping to prove the polls wrong.

The one who'd like to think the polls are right is Michael Nutter. He, like the others, was greeted by another poll showing him with a substantial lead heading into the voting tomorrow.

A new survey done by SurveyUSA for NBC10 had Nutter at 36 percent, Tom Knox at 25 percent, Chaka Fattah at 13, Bob Brady at 12 and Dwight Evans at 6. The rest of the likely voters in the survey, which had a margin of error of 4.2 percent, were either undecided or were voting for other candidates.

Last week, the Keystone Poll gave Nutter a 10-point lead over Knox.

On this final day, the candidates were holding rallies, shaking hands at transit stops, walking commercial corridors, going to shopping malls, and doing anything they could to attract the attention of the electorate.

At lunch time, Fattah addressed a rally at Broad and Spruce, Brady and Knox worked the Reading Terminal Market, Evans campaigned along a commercial strip, and Nutter walked along Fifth Street in a predominantly-Hispanic section of North Philadelphia.

Polls open tomorrow at 7 a.m. and close at 8 p.m.
