I don't think that many Freepers are pro amnesty. What makes you say that? And I think that the presidential candidate who best articulates the border enforcement issue will win. Democrats and non-political persons who simply want to get their country back will cross party lines.
I seem to mainly get entangled in the amnesty threads, I am glad to hear it's not so. Rudy and McCain being very pro amnesty and apparent front runners is disconcerting. Still a long way to go.
