Of course "Help us Bush" could mean quite a lot of different things, some of them nothing to do with Dubya at all.

"I stand up and I am counted on Election Day.

Then I pay my taxes. Then I abide by the laws. I treat other respectably."

That's what they did all those years in the USSR; and in places like Iraq today. In itself it doesn't necessarily add up to democracy. There's got to be some sense in which your contribution registers.

Probably most of the people on Saturday in London voted for Tony Blair, and those who didn't pay their taxes and generally treat other people respectably. Public demonstrations are part of the very fabric of democracy, a feedback which politicians badly need. Anybody who seeks to interfere with that is a kind of traitor to democracy.
