It depends on how the question was asked. If they just said "did you vote for Trump" and anyone that said yes they just assumed was MAGA and checked off "yes", then they did not even require a poll lol.
The suggestion is that anyone who voted for him supports his decisions 100% of the time. N Koreas leader just received 99.03% of the vote for example...
CNN is not helping themselves, America, Israel or the Iranian People with rigged polls. They just stay out of it entirely if they are seeking the lowest denominator for an audience.
We need the West to win, we do not need media manipulation or bias on ANY side. The moment they see a weakness with Trump they will strike. They will certainly strike against the next GOP candidate I guarantee you that.
