With Bill de Blasio's and John Liu's runoff victories, the Post reports that City Councilman David Yassky (who lost the Comptroller race Liu) said, "I think if Mayor Bloomberg is re-elected he certainly will have very aggressive watchdogs in Bill de Blasio and John Liu that are going to be ready to challenge him when they feel it's appropriate... I think that it's likely to be a more contentious city government over the next four years." Bloomberg continues to lead Bill Thompson in the polls; a mayoral insider admitted, "It's going to get tougher with Liu and de Blasio."
