Actually after my first read I would have agreed with you but after my fourth read I have to agree with Dr. Sowell. I believe he’s looking at it from the most electable, not the one with the most conservative values.
I also believe if Fred Thompson throws his hat in the ring it’ll change his assessment, I think Thompson would win it all.
Giuliani is not electable because he's too Liberal and has too much baggage. Should he get the nomination, the MSM will eat him alive and will leave Hillary alone. Furthermore, he'll do a lot of damage to the Republican Party, ruining the platform and splitting the party in two.
Thompson isn't even in the race, and the latest polls show him beating Hillary by one percent. He is likeable, and the character he plays on TV will only help him in this regard.
Thomas Sowell is a brilliant man, but brilliant men can be wrong and here Sowell is completely wrong.
The two most electable men are Thompson (if he get in the race) and Romney, who needs some more exposure, but who when he gets it, will also surpass Hillary in the polls. And neither of the two has Giuliani's baggage.
