While some cynics still view Barack Obama’s appeal for “change” as empty rhetoric, it’s starting to dawn on Washington insiders that his ability to raise vast sums of money from nearly one million mostly small donors could shake the grip that special-interest money has long held over the U.S. government.

This spreading realization that Obama’s political movement might represent a more revolutionary change than previously understood is sparking a deepening resistance among defenders of the status quo – and prompting harsher attacks on Obama.

Right now, the front line for the Washington Establishment is Hillary Clinton’s struggling presidential campaign, which has been stunned by Obama’s political skills as well as his extraordinary ability to raise money over the Internet. Obama’s grassroots donations have negated Clinton’s prodigious fundraising advantage with big donors.

Powerful lobbies – from AIPAC to representatives of military and other industries – also are recognizing the value of keeping their dominance over campaign cash from getting diluted by Obama’s deep reservoir of small donors. It’s in their direct interest to dent Obama’s momentum and demoralize his rank-and-file supporters as soon as possible.

So, neoconservatives and other ideological movements – heavily dependent on grants from the same special interests – are now joining with the Clinton campaign to tear down Obama by depicting him as unpatriotic, un-vetted, possibly a “closet Muslim.”

On Feb. 25, the New York Times’ new neocon columnist William Kristol attacked Obama’s patriotism by citing the Illinois senator decision to stop wearing an American flag lapel pin because, Obama said, he saw how George W. Bush was exploiting the flag to stampede the nation toward war with Iraq.
