Former NYC Mayor Rudy Giuliani endorses Chris Christie for New Jersey Governor

Really, does this matter to anyone? Do endorsements like this change any votes? Other than having the bad taste to endorse Christie outside the apartment complex in Hoboken where current Governor John Corzine lives, will Rudy have any impact? One question The Jersey City Desk has is does Rudy's BFF Bernie Kerik also support Christie? If Christie does become Garden State Governor we'd hope he'd be one helluva lot smarter and make better decisions than Rudy Giuliani did.
