The idea here it seems is to ask a question to allow an opponent to shine and take votes away from a more potent foe. Romney lets Rudy show his stuff on China. Yup, get some of those McCain votes. McCain asks Huckabee a FAIR tax question. Let him grab some of those middle and lower income voters from Romney. Interesting. UPDATE: However, Huckabee does ask Romney a tougher gun rights question, revealing that my “running for McCain’s VP” theory may be holding up.
