Yesterday, John Edwards “won” the support of the New York Chapter of the Transit Workers Union. He even showed up in the city to rejoice with Roger Toussaint, who represents up to 34,000 union votes in the region. We can’t help but think, though, that this public display of affection might not have been the best idea. In a city where Barack Obama and Hillary Clinton already have an edge — why affiliate yourself with a shyster who is most famous for inconveniencing millions of New Yorkers for no legitimate reason with the illegal transit strike in 2005? Hillary’s lucky she dodged this bullet. Edwards probably assumed that New Yorkers who feel good about unions outnumber those who are still irritated about the strike, forgetting, of course, that we city people are like elephants. We have long memories, and we think it’s a real bitch to walk from the Upper East Side to Wall Street.
