Bridgegate?

Bridgegate? I thought this issue had already run it course through the scrutiny of the media, but I guess not. This issue still has no standing the Chris Christie was behind it and seems to only still be around because of the "word on the street" that he is considering a Presidential bid in 2016. I wonder, if Christie announced that he was not going to be running for President, how quickly would this "scandal" disappear? It has become monotonous at how long this has been going on. What is the reason the left will not let go? Are they intimidated  at the thought of Chris Christie taking a shot at the Presidency?
