This display by the President et al and the theatrics in the Senate were nothing more than political grandstanding to give the appearance of doing "something" in the wake of a terrible tragedy. But there was absolutely NOTHING in any of the proposed gun legislation that would've prevented the tragedies in Newtown, Colorado, Virgina Tech, etc. The bill and its amendments were about nothing more than making it more difficult for law-abiding Americans to buy a gun. Instead of passing ever more restrictive, costly legislation, how about enforcing the laws currently on the books at the Federal, State, and Local levels?
As for the bull-squeeze displays of anger, tears, and scowls from Barry, DiFi, Biden, etc: It would've been nice to see those kinds of displays of GENUINE anger in response to the attacks on and murders of Americans in Benghazi and Boston, or say, the massive amount of murders and gun-related crime in his "hometown" of Chicago-which already has some of the strictest gun laws in the country.
The only thing Obama's probably really angry about is that yesterday's vote threw a wrench in his/the Democrats' plans: I'm sure he/they were counting on the gun bill passing the Senate, knowing that it would be dead on arrival in the House; and then they could use that failure in the House as leverage (along with their propagandists in the media) to retake the House in 2014.
Yesterday's vote in the Senate may not have completely neutered Obama politically, but with all of the effort he, Biden, and their minions put into it, it WAS a serious kick in the nuts to his political cred.
