Having answered phones all day in a poltical office, a Congressional District office, for a whole summer, I have to say that a Tancredo candidacy should be taken very seriously.
The most calls we got on a single issue on a single day was the support calls we got when the Border Patrol did sweeps to pick up illegals. The second most calls were the complaint calls we got when the BP stopped the sweeps.
Let me say this with confidence, not arrogance, to anyone who doubts this man, Tancredo. He can win the Republican primary. The immigration issue has such a base of anger in the GOP, that its a powder keg waiting to blow. I'm not saying he will win, but he aboslutely can, and anyone who doesn't think so doesn't know jack squat about the Republican base.
Tancredo could possibly win the primaries in all of the border states and CO (Provided Owens doesn't run), but those primaries come into play too late for his political aspirations. However, he could take AR which will be voting early this time.
