On the candidates' foreign trips

As details begin to leak about Obama's forthcoming trip to Europe, Britain, France, Germany (questions about the Brandenburg Gate appearance,) then following on to Jordan, Iraq, and Israel (do they let black people go to the Wailing Wall?,) I find myself thinking about the comparisons McCain avoided by making his foreign trip to Mexico and Columbia.

Will the crowds in Europe come out in huge numbers for Obama? What's their tone? If McCain had made the same Europe stops, how much anti-Iraq, Guantanamo, etc protest would there be in the streets?

I think the McCain camp wisely chose to dodge that bullet.
