Not a baker, so if there are holes in this, it all my fault.

From article:

The number of registered voters in Connecticut has reached 2.16 million. That's higher than Secretary of the State Denise Merrill can remember it ever being for a state of 3.5 million people.

Between November 2016 and Oct. 31 of this year, 107,104 new voters have registered as Democrats, 51,485 have registered as Republicans and 155,040 have registered as unaffiliated voters. That brings the total number of Democratic voters in Connecticut up to 791,603, with 462,948 Republicans and 876,517 unaffiliated.

So digging a bit deeper:

62% (2.16/3.5) of the CT population is registered to vote, i.e. over 18.

US census data based on 2017 numbers has the following information (see graph)

https://www.census.gov/quickfacts/fact/table/ct,US#viewtop :

20.7% of 3.5 million is 724.5K and we can estimate that the eligible voting population in CT is 3.5M - 724.5K = 2.7755M. We then find that 79.3% of the eligible voting population of CT has registered to vote.

79.3% or just shy of 4 out of 5 people in the state (and 11.2% of these registered in the past 2 years). This amazes me to the point that I find it hard to believe.

I haven't done this number crunching for any other state yet and am interested to find out what their % voting eligible / registered would be now and what it looks like historically.

This election is closed but could be ammo for the next.
