While I only saw it as an attachment to an email by a stranger, my favorite Obama bumper sticker image was a picture of his face with the legend: "You are going to be very disappointed."

Here's an extended riff on that theme from the progressive left maverick Alexander Cockburn in the UK Independent. Excerpt:

Obama invokes change. Yet never has the dead hand of the past had a "reform" candidate so firmly by the windpipe. Is it possible to confront America's problems without talking about the arms budget? The Pentagon is spending more than at any point since the end of the Second World War. In "real dollars" – an optimistic concept these days – the $635bn (£400bn) appropriated in fiscal 2007 is 5 per cent above the previous all-time high, reached in 1952. Obama wants to enlarge the armed services by 90,000. He pledges to escalate the US war in Afghanistan; to attack Pakistan's territory if it obstructs any unilateral US mission to kill Osama bin Laden; and to wage a war against terror in a hundred countries, creating a new international intelligence and law enforcement "infrastructure" to take down terrorist networks. A fresh start? Where does this differ from Bush's commitment on 20 September 2001, to an ongoing "war on terror" against "every terrorist group of global reach" and "any nation that continues to harbour or support terrorism"?

Obama's liberal defenders comfort themselves with the thought that "he had to say that to get elected". He didn't. After eight years of Bush, Americans are receptive to reassessing America's imperial role......

Whatever drawdown of troops in Iraq that does take place in the event of Obama's victory will be a brief hiccup amid the blare and thunder of fresh "resolve". In the event of Obama's victory, the most immediate consequence overseas will most likely be brusque imperial reassertion. Already, Joe Biden, the shopworn poster boy for Israeli intransigence and Cold War hysteria, is yelping stridently about the new administration's "mettle" being tested in the first six months by the Russians and their surrogates.....

......In February, seeking a liberal profile in the primaries, Obama stood against warrantless wiretapping. His support for liberty did not survive for long. Five months later, he voted in favour and declared that "the ability to monitor and track individuals who want to attack the United States is a vital counter-terrorism tool".

.................

Obama's run has been the negation of almost every decent progressive principle, with scarcely a bleat of protest from the progressives seeking to hold him to account. The Michael Moores stay silent. Obama has crooked the knee to bankers and Wall Street, to the oil companies, the coal companies, the nuclear lobby, the big agricultural combines.......

So no, this is not an exciting or liberating moment in America's politics. If you want a memento of what could be exciting, go to the website of the Nader-Gonzalez campaign and read its platform on popular participation and initiative. Or read the portions of Libertarian Party candidate Bob Barr's platform on foreign policy and constitutional rights. The standard these days for what the left finds tolerable is awfully low. The more the left holds its tongue, the lower the standard will go.

A similar argument applies for libertarians who are enthusiastic supporters of Obama--or McCain, for that matter.
