You probably know what Democrats and Republicans are. There was a time when I didn't know what libertarian was. It sounded like "liberal". (In the rest of the world the words "classic liberal" means what "libertarian" means here in the US.)
Libertarians believe in individual freedom, free markets, limited government, peace, and personal responsibility. It's not strange. Many see it as an alternative to left or right that feels comfortable against their own ideas. If you were interested you can easily look up more.
I thought I'd use Think Daily to tell people about it, because most people have no idea. I promise not to make Think Daily a political forum. Think Daily is about ideas and you - and many important ideas also happen to be political topics.
