Well, you don’t have to guess because that’s part of the statistics as well. 40% of the people polled were 44 and under. Also, they weighted the poll to help account for age. It’s not like professional pollsters and statisticians don’t know how to account for these sorts of things.
I know it’s scary that if the election were held today, Trump would have a very real chance at winning, but that’s the reality we live in. And right now, it is because Biden is such a weak candidate. A lot can change in 1 year. I hope that when it comes down to it, people will do the right thing and not vote for the insurrectionist. However, we have no reason to believe they will.
