I will see if I can find out the breakdown of nations that Trump's Twitter support is coming from. Yes, one would think that Trump's Twitter support would be saturated here in the U.S.
A huuuge proportion of Trump’s base is not and has never been on twitter. I’m typical of them. Example. Wayne Allyn Root’s June 24, 2016 article that swung the Evangelical vote went viral in prayer lists of 25 and 45 names per list.
I will bet that more prayer lists were forwarded by email than by all the social media combined.
Even those Trump supporters who have a social media account.... how many and how often do they go to the big social media? My daughter gave me a Facebook account. I never go there. And she never goes to FB either.
As with the old telephone polls that missed people not sitting beside their landline, the new social media counts are interesting and informative. But not a complete picture.
Great additional comment and thanks for your work on this list.
