There's egg on the face of mayoral hopeful Anthony Weiner, who has been front and center in the fight to keep Wal-Mart out of the city. (The New York Post has dubbed him "Mr. Anti-Wal-Mart") It turns out that Weiner has pocketed more than $30,000 from two families with close ties to the big box retailer. That's not good news, considering that he's one of the sponsors of "Wal-Mart bashing" legislation that will be voted on in the House of Representatives this week.

Is the timing of the Wal-Mart revelations a coincidence? Probably. As the summer heats up, look for the candidates vying for Bloomberg's mayoral post to ratchet up their campaign vitriol. Try to stay clear of any drive-by mudslingings.
