Latest poll has Murphy down by just 2%. This decision is ridiculous. Defeat of Rubio would be a symbolic victory in a number of ways although Murphy himself doesn't seem to be much, if any, better:
1.It would mark an end of the Tea Party.
2.It would mark an end of the supposed Republican Party Great Latino Hope.
3.It would be a defeat for shallow, mindless talking point politics perfectly embodied by the shallow, mindless Rubio.
One would have to assume they know things we don't. Perhaps Rubio's lead is bigger and more durable then public polls suggest. If Rubio was constantly performing so weakly in more accurate internal polls, it's hard to see them pulling out.
On the other hand, maybe his lead becomes smaller and he becomes more vulnerable
after they pull(ed) out, in which case it makes their decision a huge blunder.
