Probable a couple will drop after the first primary, another few after super Tuesday, and one or two stick it out to the bitter end. If I had a guess, McCain and Huckabee out on Feb 6th. Paul in it to the end. Brownback out earlier, rather than later. Hunter...I dunno; probably depends on Thompson’s traction. Tancredo throws behind whomever is pushing the border issues hardest.
From a Repub point of view, you may be right.
I am deliciously smacking my lips at the thought of the Dim side however. Dims are so emotionally single issued they may have lost sight5 of the forest due to the trees. They are so fixated on GWB, they have become the proverbial “boiling frogs”.
