‘How many of these sorts of people has he attracted so far...that one 78 year old guy?’
If it were possible to add up all the people who have attended Trump’s rallies, I wonder what percentage that one guy would represent.
Realistically, statistically one cannot state the percentage that “sort of people” are by the actions of one person.
No one believes that there is just ‘one’ in those large crowds that are as angry.
