I'm no fan of Christie, but you're wrong on this one.
There's no way in hell Christie would have spent nearly two hours at an unscripted press conference dealing with the fallout over the "bridgegate" incident if there was even a remote possibility that there's any evidence linking him to it.
Evidence? Where's the "Evidence" of Obama's ties to Benghazigate or Fast and Furious?
By using your standard and Christie's "I didn't know about this until I read it in the newspaper" excuse, Obama is as clean as a whistle.
Christie is a Lib in a corrupt Liberal State. Using political power to punish your enemies is the natural state of things in a place like New Jersey. And Mafia bosses always cover their tracks.
In my area, there are often road or bridge closures. It snarls traffic, causes huge delays. People have probably died because of it.
Someone decided when and where these closures would occur, and the politicians usually only participate in that they give out the funds that allow it.
You don’t just take a crew onto a perfectly maintained bridge and do repairs for no reason. I suspect this is more a a political attack by the Clintons and their friends in the media than it is an attack by Christie on his opponent. How would this bridge closure hurt the ‘political foe’ ? The political foe didn’t ‘close’ it.
