Wasn't Nadler involved in something equally despicable back in 2000, or shortly thereafter? I seem to remember that he was.
Nadler was involved with the Million Mom March, which was caught using tax exempt money for electioneering.
Nadler was one of better-remembered participants in the 'Rat demonstrations in Florida accompanying the presidential vote recount in Florida in 2000. That's when he infamously stated, "I detect a whiff of fascism," referring to counter-demonstrators supporting Bush's position.
Despicable, yes, but hardly uncommon for remarks like that to come from a far-left 'Rat politician in the past decade or two.
