You are absolutely correct. That comes from the 12th Amendment to the Constitution. Boy, those guys in the 1700s and 1800s were huge visionaries. I’m glad they were.

Think about this: in 1785, they decided that ANY new state out of the NW territory should have no more than 5 and no fewer than 3 states created out of that.
Think of 1 state: MI-WI-IN-OH-IL and the # of reps it would have. Or think of 25 states in this area with 2 senators each!
Yet at that time they didn’t have EITHER a House or Senate!
