If you've read his book, one thing that stands out is that he constantly and consistently examines his stances and views, and is willing to negotiate with the other side to come to compromises. 'Compromise' means that you back off of your stance somewhat.
If you want a hardline politician who won't abandon any stance, then no he's not your guy. I personally like someone who is willing to adjust stances, negotiate settlements, and continually examine his own beliefs.
