So, there are some people who want to make some big changes in government but they still want to keep some of the old ways of doing things. These people are called "revolutionary conservatives".
Now, some of these revolutionary conservatives got together and formed a group called a "caucus". A caucus is like a club where people who share the same ideas can work together to make those ideas happen.
This particular caucus is called the "revolutionary conservative caucus". They believe in things like limited government, lower taxes, and more individual freedom. They want to make big changes to the way the government works, but they also want to keep some of the old traditions and values.
So, think of it like a group of people who want to make a lot of changes but still want to hold onto some of the things that made our country great in the past.
