“because I think he can make a broader connection than Mitt Romney”
I think that is one of Newts strengths. He can connect to the average voter in terms they can understand and bypass the msm. I believe Reagan and Christy also have those qualities. Another is he has kept his attacks on fellow Republicans to a minimum. Third is he has enough conservative credentials to be to the right of Romney. He is not scared to take on all comers in a debate/discussion of the issue such as the recent Newt/Huntsman debate in New Hampshire. IMHO these are the reasons he is in the lead.
EVERYONE has enough conservative credentials to be to the right of Romney. Unfortunately, it looks like we're settling for a 'progressive'. Again.
