I am still behind what I said.
This people will not vote for him. (nation)
"people" here consists of stupid idiots only. No differences between them.
(People in Norway would vote for him. People in Sweden would do the same. But here this people won't.)
That's what I meant.
The sentence describes the whole group I mentioned.
They are all so stupid that will not vor for him but a criminal as they do for decades here.
Using the word people like a true plural of a person I would say
These people will make the bridge. (I respect all of them personaly)
but
potato can be countable and uncountable noun.
people could be the same.
This people I see as a mashed potato in a dish.
Either personaly or together they are a food for the politicians.
So it is a mashed potato, nothing else.
No any personality to distinguish.
Then it is an ucountable noun.
