It's hard to see how some of his over-the-top supporters could not end up being disappointed. (One suspects much of Europe will end up the same way.)
And does this election make it more or less likely that Israel will do something about Iran?
All will be revealed in due course...
UPDATE - miscellaneous further comments:
* Not many people have been saying it yet, but the popular vote for McCain was higher than many polls predicted, and actually not too bad given the financial crisis. Surely that alone must have shaved at least one or two percent from his popular vote.
* I've made the point elsewhere, but if I were a Democrat, I would be a little worried that such widespread success in both the legislative and the executive arms of government (and the likely liberal lean of the judiciary in future appointments) is going to make it near impossible for them to disclaim responsibility for anything that goes wrong. Truly, if anything gets broke now, they own it.
* Am I the only one who thought Obama seemed a little too dour in his victory speech ? I genuinely don't understand the accolades given to him as a orator. He's competent, but I really think you've got to be "of the left" to be overly impressed. To make a comparison, the oratory of John F Kennedy also dealt with lofty and idealist themes, and did genuinely impress; but at that time, the fate of Western democracy was by no means assured. Speaking of freedom, self sacrifice, human rights and dignity really had some significance to the entire world.
Obama-talk, on the other hand, is just internal politics - complaining about division, promising solutions to difficult and near intractable problems without any detail at all - dressed up in emotional generalities.
* Nevertheless, this post at Tigerhawk sums up well, I think, the generally magnanimous attitude that most of the right wing commentators take towards the Obama win. They do recognise the significance of the symbolism of a black man being president. It is a million miles from the bitterness, accusations and overwrought emotion the left were threatening if they didn't get their way.
* This post at Bryan Appleyard's blog makes a good comparison:
Obama is a hope candidate, and like all hope candidates (Blair being our most recent), he is doomed from the start by absurd expectations and by his own limitations.* The other "glass half full" way of looking at it is that Democrats and Bush critics generally have bitched and moaned about the job being done by a US president who really has had the most extraordinary challenges to face. Now with an emphatic win, they've got the keys to the car and (one can only hope) might at least develop a bit of humility and realistic appreciation for the difficulties and imperfect nature of all governments.
UPDATE 2: Currency Lad's post this morning about the hypocrisy of the Democrats as "unifiers" makes the point more eloquently than I can.
