American democracy has been hacked.

The role of campaign contributions in our political system and the role of lobbyists have now reached levels that are quite unhealthy for the operations of our democracy. But the antidote, as in past eras of lobbyist excess, is for more involvement by citizens to build pressure on members of the House and Senate to serve the public interest.

There's no doubt that in the last two to three decades, American democracy has been hacked. It was based on the regular harvesting of the wisdom of crowds, but now big sources of special interest money are able to prevent the passage of almost any meaningful reform that's aimed at the public interest.

The United States is the only nation that can lead the world toward a solution on climate change.

Fear is the most powerful enemy of reason.

Hey, you know what, I've gotta go on that 'Letterman' show. That show is so lame.
