You could be right about the difficulties in polling particularly when we have a race like this one that features (love ‘em or hate ‘em) two very polarizing figures.
That said, there is no reason why polls like the USC Poll can’t turn out to be fairly accurate. These polls measure changes in the voting intentions of a fixed and large population of voters over time. That is very different than your classic telephone survey that, as you pointed out, is inherently a flawed methodology.
Will it happen that the USC Poll calls it right? Time will tell. If we really are looking at a big movement to Trump from the sick and corrupt Hillary over the next 70 days it will be visible in that poll.
Fingers crossed.
“If we really are looking at a big movement to Trump from the sick and corrupt Hillary over the next 70 days it will be visible in that poll.”
You could very well be correct about the USC poll and its new methodology. I suspect the old, land-line-based polls are worth than useless.
