Biden will lose with a lousy 2-point national lead in that sample.
Why?
1. The Electoral College. 2. Enthusiasm among Trump voters.
Anyone worth anything in this game knows that 2-point lead cannot survive that big an enthusiasm gap.
That spread almost mirrors our polling four years ago, precisely. In fact, reason our national wasn't as accurate as states is because...
The "Blue Wall" (I don't believe in walls), the battleground states and even Dem-edge but not solid states like MN, CO, VA.
