WFP's indefatigable Dan Levitan emails over this shot from this morning's pre-canvass rally at WFP Galactic Headquarters.

By any measure, WFP has launched an impressive effort today and added luster to its claim to be the state's premier GOTV organization. The Working Families Party took sides in four primaries today - SD-25, backing Squadron over Connor, SD-61, Joe Mesi over two others in an open-seat race that could get very hot, SD-21, Parker over two potentially disloyal challengers, and AD-64, where they've cast their lot with Assembly Speaker Shelly Silver - and in the course of their efforts by their own estimate knocked on 125,000 doors. In all, Dan Cantor has 400 ground troops active in these races.

Agree or disagree with WFP on a given race or issue, but don't ever doubt their effectiveness.
