There is no way all 20 are going to be asked the same question. That would give room for maybe 5 questions, and skip the opening and closing remarks.
This show is for the press to do what it's told, take out certain candidates, and promote others.
But that’s the thing. Ever hear a modern Democrat talk? They ALWAYS circle back to the talking points. So if they all start with the same talking points, they’ll all repeat them, with the actual questions only guiding which talking point each one uses at any given time.
We could have talking point BINGO cards, with the candidate names filling in the boxes. Each card would be for a specific talking point, and if your card scores 5 in a row first you win!
