You're right -- I do know it. But that's not the point. The point is that the Dems love to have talking points, and all the better if they're provided by a pseudo-Republican like Tancredo.
Seems to me they're being provided by the Republicans' Mexican foreign policy decisions. But shoot the messenger, huh? Tancredo is really irrelevant in the whole thing. Whether he's there or not, the problems still remain and people are still pissed about them.
