politics of the united states

there are three branches - executive (president), legislative (senate and house), and judicial (supreme court).

the house has 435 districts, and you vote for one representative for your district. each state gets the number of districts based on its population compared to the country as a whole - some states only have one, and california has the most - around 50. representatives get 2-year terms.

the senate every state gets exactly 2 senators, for 100 total. population doesn't matter. senators get 6-year terms, and each state's senators are elected in different years.

when you vote for the presidency, each state has "electoral votes" equal to the total number of representatives and senators that state has. whoever gets the most votes in your state wins all of the state's electoral votes, and whoever gets the most electoral votes becomes the president. the president gets a 4-year term, and the maximum is two terms.

laws are passed as follows: the house has to pass it, then it goes to the senate. if the senate passes it, it goes to the president. if the senate doesn't pass it, it goes back to the house for changes, until there is something both houses pass.

the senate has an unusual rule called the filibuster, where one or more senators who want to block a bill being discussed can just keep talking and talking and not stop to allow a vote on the bill - it takes 60% of the senate to vote to stop a filibuster. so if you have 41% of the senate opposed to a bill, you can effectively block it - this gives the minority party a lot more power than it would normally have.

once the president gets a bill that has been approved by the house and senate, he can sign it, and it becomes law, or he can veto it, which means that it goes back to the house and senate and it fails unless they both pass it by a 2/3 vote (called "overriding a veto").

even if the house, senate, and president agree to pass a law, the supreme court can strike the law down if the law violates the constitution.
