Where did the polls come from? Oh, the same polling company in 2016 Presidential election. Hard to believe they are still around
Huh, I'm guessing you're replying to me? the pie charts come from the Dealey Plaza eyewitnesses themselves, there is CT(Thompson) and LNer(HSCA McAdams) pie charts and apart from a few different interpretations, the numbers are basically the same.
PS use the quote function, that's why it's there!
