Joe Biden clearly smells blood in the water. That is why he is out expressing his regrets with not running, his praise for Senator Bernie Sanders and his belief that The Donald could actually win.
All designed to further undermine guess who.
Conventional wisdom is if Sanders wins Iowa and NY, the big boys will take over. Don't be so sure Joe. The mood this year is against the old guard and Joe Biden is part of that.
However, suddenly the Democratic race is getting interesting again. I like that.
