Queues
Long queues at polling places are a sign, surely, of a country recently freed from tyranny, of one that is experiencing the chance to vote for the first time (I'm thinking of South Africa in 1994, for example). They are not something that you generally expect to see in a mature democracy like the USA.
Let’s hope, then, that the people streaming to the polling stations on America are those desperate to breathe free of Bush and the Neocon hegemony, and not tiny-minded racists trying to drag the country back to the dark ages.
And remember, America: the whole world is watching.
