Chris Christie is calculating and perhaps living for another day. Whether you like his politics or not, you have to like Chris Christie, a little. He seems to be very passionate about what he believes, however he has alienated many women. Polls say the men like him.
The guy is very blunt, sarcastic, and to the point, those are all likeable qualities, to some. He says what he means and means what he says. He also is slightly left of center Republican, who in these days and times is not really a great place to be if you are a Republican, nearly all are far right.
But I think Christie is smart to pull out of the race. Although Obama has his problems, I believe it will be very, very hard for a Republican to beat him even in this economy. Christie proves he is very prudent, reflective, and realistic about his decision-making. He will be a player in the future.
