This is a must-read on the history of classlessness of Obama from the campaign to the British, to Israel:

"On Tuesday, the White House released a photograph of President Obama nonchalantly leaning back in his chair with his feet on the desk, the soles of his shoes clearly visible--as he spoke on the telephone with Benyamin Netanyahu, Prime Minister of Israel.
"In April 2008, he was caught on tape during a debate with Hillary Clinton, rubbing his hand across the right side of his face and extending his middle finger in an obscene gesture that many in the audience could see it but she could not, and when this provoked laughter on the part of his supporters he responded with a knowing smile."

And so on.
