All I'm saying is that if Obama becomes president and does a great job, people of all political stripes should acknowledge it. Same with McCain.
As for McCain, a major concern I have is this so called "maverick" who is supposedly a mild-Republican who bridges the gap between (American) liberal and conservative has made a major departure from his 2000 campaign and what I see as his true political beliefs to pander to appeal to the Republican base.
Finally, were you to ask a group of left wingers if Obama was a left winger, you'd probably get differing answers, but the most popular I'd bet would be no.
The American people need to understand that their political climate is different from the rest of the world and is skewed to the right - when they call someone a liberal, they are typically still right wing or possibly centre-right, Fox has called moveon.org a far left group and that is a vastly incorrect statement (not singling out Fox). A conservative in the US is often someone on the mid-right to the left edge of far-right - so the more radical of the two major parties(I use radical in this sense as being close to the extremities of the political spectrum, but I believe the word in actual political theory has another connotation) in American politics is not the Democrats and Obama, but the Republican party - someone like Bush would be a very good example of someone nearing right-wing radicalism / the far-right.
I don't really think Obama is an actual left winger in the way the Canadian NDP is - and the NDP is only very mildly left typically. For all intents and purposes he is a centrist / centre-rightist (centre-right probably most accurately) and one of the very few actual left wingers in mainstream American politics would be Dennis Kucinich.
