It seems that progressives and jounalists (but then, I repeat myself) are concerned that the national media polls don't accurately reflect the will of the people. Well, they have been wrong before.
I remember going to bed one night, thinking that Hillary Clinton would be our president, but waking the next morning to learn that Donald Trump had won decisively in the race. Lots of folks were shocked at that result, and they haven't gotten over it yet. Then, there is the old Dewey beats Truman example.
The Republicans can't get cocky. They have to run right up to the finish line. But, we're seeing some weird stuff this cycle and the only poll that matters is the one that takes place on election day.
I am no analyst, but I've seen the polls wrong before. Stay the course. Run the race.
