High School Political club

Some students at my school seem to be interested in politics and me and some friends are thinking about trying to make a club in which we can discuss and learn more about government and current issues...
Question:
How do you get these clubs started?
What all could we do in this club?
Thanks

You usually need a teacher to 'sponsor' your club.

And make sure that that teacher is one who all of you will feel comfortable with.

Well I don't know if you have this or not but in my school we have a United Nations club. I don't know if that is what you are talking about, but if your school doesn't already have it, then you should do some research on that.
Now I do agree with the other two that replied previously: Make sure you find a teacher (or someone of authority) that wouldn't have a problem with starting something like that. Since there are many topics on the news, internet, and this very site, I would say that you and your friends could take like ten minutes at the start of the club to find an interesting or popular topic. After that, you all could start a small discussion/debate on it. If it is a problem, then you all could try to discuss a solution to it...
The possibilities for such a club are endless.
