The votes are in. Hillary Clinton is going to be the nominee for President for the United States. Rather than fracture a Democratic Party that so desperately needs unity right now to face down the threat of Donald Trump, I suggest Bernie Sanders be the next Senate Democratic Leader of the United States of America.
PUMAs, for those who have forgotten the 2008 Democratic primary race, were the supposedly-numerous Hillary Clinton supporters who refused to back Barack Obama. The name stood for "Party Unity My Ass!" which was also their rallying cry. This year, they may be replaced by the "Bernie Or Bust!" crowd, or (to coin a neologism) the BOBs.
