A presidential campaign unlike any other ends on Tuesday. Here's how we got here

The presidential campaign has featured two assassination attempts, a criminal conviction, the late departure of one candidate, and a replacement candidate who could be the first female president. Now, Americans will choose between Donald Trump and Kamala Harris. It may take days to know the final result, which could be just another surprise in a campaign that's been full of them.
