Okay kiddo, think of the whole country as a big coloring book. Some people like to color with red crayons and some people like to color with blue crayons. When it comes to politics, some areas of the country are known for having more people who prefer one color or the other.
So, the states that tend to have more people who vote for the Republican party, which is often associated with the color red, are called "red states". That means they are colored red in our coloring book. And the states that tend to have more people who vote for the Democratic party, which is often associated with the color blue, are called "blue states". That means they are colored blue in our coloring book.
But it's not just about colors, it also has to do with the political beliefs and values of the people who live in those states. For example, red states might be more supportive of ideas like lower taxes and individual freedoms, while blue states might be more supportive of things like government-provided healthcare and protections for minorities.
Overall, it's just a way to describe and understand the political differences between different parts of the country. And just like how you might have friends who like different colors than you, it's okay for people to have different political beliefs too!
