Okay kiddo, so a debate is when some people want to be the boss of something, like the whole country! So they talk to each other and say what they think about things, like how to make our country better.
CNN and YouTube are two companies that help make this happen. They get some of the people who want to be the boss of the country to come and talk on TV. They ask them questions and the people have to answer them.
Lots of people can watch this on TV or on the internet. People can also ask questions to the people who want to be the boss through YouTube.
This helps us decide who we want to be the boss of the country. But remember, we all have to vote for who we want to be the boss!
