Without Weiner, Who Comes Out for the Democratic Primary?

If Anthony Weiner drops out of the mayor’s race (Tony Avella notwithstanding!), it could leave New Yorkers without a competitive Democratic mayoral primary, driving down turnout for everyone on the ballot.
Jerry Skurnik, a political numbers cruncher not affiliated with any campaign, said a Democratic mayoral primary featuring both Anthony Weiner and Bill Thompson could have drawn between 500,000 and 600,000 voters. Now, with Weiner looking like he may drop out, Skurnik said he predicts about only 400,00 voters to hit the polls during the September primary.
Who does that help?
“Two groups helped by lower turnout are candidates who are well-known or have organizational support,” Skurnik said.
