ELI5: Explain Like I'm 5

Missouri bellwether

Okay little one, do you know what a bellwether is? It's like a sheep that has a bell tied around its neck so the other sheep know where to follow.

Now, imagine Missouri is like that sheep with the bell. In this case, Missouri is a state that is known for being a good indicator of which way the whole country might vote in an election.

So, people pay attention to how Missourians vote because they think it will give them an idea of how the rest of the country might vote too. It's kinda like Missourians are the leaders of the flock and everyone else follows their lead.

Does that make sense?
