1. In the US, after you vote you get a sweet sticker.
And you can put the sticker on your face and look cool all day.
You don't get a sticker in the UK.
2. The UK ballot is as simple as this.
An American one will usually look more like this.
3. In the US, depending on what state you're in, you either have to feed your ballot into a big machine...
...or use an electronic voting machine...
...or something else scary and complicated.
In Britain, you just, like, stick it in the box.
4. In the US, there are pretty strict rules about how to actually mark your vote.
This was the root of much chaos in the 2000 presidential campaign and Florida's "hanging chads".
In the UK, though, the rule is only that you have to express a clear preference on the ballot.
So, like, you can literally draw a dick in a box and it counts. Probably.
5. In the UK there are strict rules which pretty much prevent broadcasters from discussing the election while polls are open.
It's a bit less strict for non-broadcasters like BuzzFeed.
