Why is Obama sad  and blowing his horn with the Paris Climate Agreement ? 
Guys beginning to sound a like  Al "Climate Change" Core.Brah!

 Climate Change/ Paris Agreement  was Obama's  baby,  it was not passed by congress,thus any sitting US president after him,can strike down this agreement,because it's not a.......... Treaty.
Which brings to mind....If Congress holds the  purse why was he allowed to give Billion of US dollars to this lost cause. Hummmmmmmm.
 I conclude that his sadness is the result of another one of his Legacies biting the dust.IMUA!
