Hello, this is video shows most recent makeup of senate including victory of 
Doug Jones.

Short info:

This is timelapse I created showing history of USA Senate, how they swithed from party to party from 1789 till 2018. For this project I decided to split all states into two parts to show both of two seats each state have. I find this method more useful than using stripes ar mixed color (aka purple for dem/gop) in times when state senators were from different parties, also this way I could show the history of each individual seat so I put numbers denoting which senate classes seats belong to.

If you dont know senate classes are for determining when particular senator face re-election. All classes have re-elections two years apart or put it other way one third of senate is elected every two years.

This video also show senate vacancies, but only long ones (nearly a year, years), vacancies that only lasted days, weeks or a few months arent shown due to timeframe of my video being one year althrought there were many of them in almost all states.

I also added names of serving presidents, vice presidents and speakers of the house in each frame. Senate majority leaders only appear 1920s because that title didnt exist before 1920s.
