Good for Allen. Shows that he's gaining national appeal. I could see an Allen/Gingrich ticket in 2008.
I still don't see how 61 votes shows anything about anyone's national appeal, but I do agree that he is a viable candidate for the nomination.
National appeal in the sense that Wisconsin is not Virginia, so if he can poll well in a different state, that means his appeal is not just regional. Of course, I don't think anyone has done a state-by-state poll on all the leading GOP candidates, so we can't tell how far out Allen's appeal goes.
