I read this night and I thought to myself why did this happen? Then I remembered the immigration vote a couple of months ago. Rubio sided with John McCain, Lindsay Graham and Chuck Schumer. A death blow if you ask me.
What was Rubio thinking? That people would forget? New Hampshire is full of conservatives that follow politics very closely. Additionally, they have an early primary. A bad showing in NH is not good.
Can he rebound? Its still early for 2016.
