The union in question is the International Association of Firefighters. Its president, Harold Schaitberger, is a “longtime supporter” of John Kerry and donated two grand to Waffles’s campaign in 2004 — although there’s at least one self-professed conservative in the mix of interviewees here and per Karol’s very informal survey, the anti-Giuliani animus isn’t a fringe thing within the FDNY.

She predicts firefighter opposition will be a big problem for him. I predict it won’t simply because unpreparedness for 9/11 was institutional throughout the U.S. and people responded to his poise in the aftermath, which isn’t affected by anything here. But judge for yourself. Here’s the clip, via the IAFF’s “Rudy Giuliani: Urban Legend” website. Damning all the same.

Update: Serve and volley.

Before the International Association of Fire Fighters (IAFF) was able to release a video in the afternoon full of angry testimony belittling Giuliani’s support of New York City firefighters, the campaign fired off releases and held a press conference.

“It’s unfortunate but not surprising that the IAFF union bosses have once again taken the low road in a move clearly out of step with their membership,” retired New York City firefighter Lee Ielpi said in a statement from the campaign…

The IAFF backed Kerry in 2004, helping salvage a listing campaign in the primaries. IAFF President Harold Schaitberger was a constant fixture behind Kerry as he took the stage in Iowa, New Hampshire and other arenas to claim victory on his way to winning the nomination…

Schaitberger and Giuliani clashed in the weeks before the 2004 New Hampshire primary, when they were in the Granite State at campaign events…

Giuliani’s campaign also pointed out that Schaitberger has held a number of roles in Democratic organizations and has contributed financially only to Democratic candidates.
