Grassroots or astroturf? Real or fake?
Those are the questions being asked about the rash of protests taking place all over the country against the president's plans to reform the nation's healthcare.
Many Congressional Democrats are facing angry constituents at "town hall" meetings.
What is meant to be an opportunity to exchange views and listen has turned into something more like a bar-room fight.
At one such meeting, the police were called in to restore order. One Congressman has received death threats, another has faced an effigy hanging by a rope.
Placards warn of "health rationing" and "socialised medicine"; chants of "Just Say No!" are commonplace.
Democratic senators and representatives - who have just gone home for the summer - may now be wishing they had stayed in humid Washington instead.
Tiny rump?
So are the "grassroots" genuinely angry, or are the protests simply manufactured "astroturf"?
That depends largely on your politics - or whether you watch the liberal MSNBC or conservative Fox News.
