Attorney General Martha Coakley continues to look strong against both her fellow Democratic candidates and against the likely Republican nominee in the Massachusetts Senate special election, according to a Western New England College Polling Institute survey conducted Oct. 18-22.

With just over a month to go before the Dec. 8 primary, Coakley leads the Democratic field with 37 percent among registered voters. In a bit of a surprise, the survey found investor and Boston Celtics co-owner Stephen Pagliuca running neck-and-neck with six-term U.S. Rep. Michael E. Capuano for second place. Pagliuca is at 14 percent and Capuano at 13 percent.

Alan Khazei, the co-founder of community service program City Year, trails at 4 percent of the vote. Twenty-six percent of voters were still undecided.
