Biden at 51 in Florida is plausible, and so is 54 in Pennsylvania. It's Trump's numbers that seem low.
Unenthusiastic Trump voters are pretty damn demoralized right now, so something like 51-47 in Florida and 54-45 in Pennsylvania come November 3 seems plausible to me.
I agree. I'm skeptical of these polls too, but Trump's percent of the vote has been tanking in most polls lately which is what's inflating Biden's margin, so I don't see why Quinnipiac is the worst thing since Zogby for picking up on it too.
