I find Newt's voice irritating. He sounds like he's talking with a mouthful of something.
However, I think HE"S very impressed with himself.
Some would call that confident in what he's saying...which to those with confidence issues mistake this for arrogance. It's beyond refreshing hearing Newt explain with clarity what he believes....what his opinion and thoughts are concerning the issues at hand. He does not go too far over peoples heads, which obviously he could do, nor does he leave the intellectuals out to dry....good balance in explaining things so all can understand where he's coming from and how he sees things.
