The last lines are perhaps the most interesting: "change comes to Washington and not from Washington", it is the people that Obama argues need to push for change. What this seems to aim to achieve is the firmly align the people with Obama against the system and vested interests. He remains in the strategic position of being the people's president acting on their behalf but fighting against a Congress and House of Representatives which contain those who represent corporations, themselves possibly but are against Obama led revolution - that is the implicit meaning of his campaign.
He presents his plan and asks his supporters, those who have shared their email with his campaign, to do all the same activities he asked of them to get him into the White House: campaigning among their neighbours, making phone calls and mobilising support behind the President. It could well be a powerful force to bring to bear against elected representatives if it works. I guess the question is will it, and can this be sustained?
