Newt has a lot of pizzass and can get a crowd energized, and a lot of good ideas. Romney will probably draw more independents and moderates. Paul is very constitutional in his approach to money and economics and foreign policy, but his achillies heel for me is his stance on Iran where he would in essence ignore their nuclear efforts and allow them to proceed unhindered. Santorum has waged a campaign of hard work and faith, and more and more people are coming around. Not "stellar" and a not a lot of glitter...but steady.
If you have a mind, please ping others to this Tracker thread.
The correct term is bellwether, not bell weather. It refers to a leader of a flock of sheep, usually male, wearing a bell that the other sheep follow.
I think Romney probably has the Idaho vote, large LDS population and all.
