It was a spiteful move which inconvenienced innocent victims, i.e., the commuters who needed to cross the bridge.
But what is the difference between that and the Obama administration's closing of the open air National Mall after the Senate and House couldn't reach a spending compromise and invoked sequestration?
That was also a spiteful move which inconvenienced innocent victims, i.e., the tourists who wanted to see the the Lincoln Memorial, WWII Memorial, and so on. The federal government saved no money by doing so, in fact it cost extra money to have people come in and erect those barriers. (They saved money by shutting off the fountains and furloughing workers, but the monuments themselves are open air monuments, and barricading them off was extra work.)
(Strangely, even though the National Mall was closed to WWII veterans who wanted to visit the WWII Memorial that week, the next week the mall was opened up for a pro-immigration rally.)
Yet Bridgegate is endlessly talked about in the media, and the closing of the National Mall is allowed to slip down the memory hole.
Obama is truly the Teflon President.
And his Teflon coating is the media.
