“Since many in the Santorum camp would never support Newt, after the derogatory nature of their treatment by his supporters”
You have it completely backwards, not to mention you just destroyed the effectiveness of the “we would have supported Newt” mantra.
Go Newt!
“Father Rick” “Ricky” “Little Ricky” just to name a few. My point is that there are significant numbers in both camps who will not support the other. The solution is no longer getting one to drop out, if it ever was. It would create even more hard feelings. The trouble is, the delegate landscape favors Romney because of proportional votes where he is weakest and winner take all where he is strongest. Short of combining the two into one campaign, I am not yet seeing a good answer. Do you?
