Well then there's no point in discussing appealing to moderates as that's not the point. You should be arguing for appealing based on geography.
Clinton won self described moderates by 12 points. Can you explain how they are winning moderates in a landslide if they aren't appealing to them?

What you really mean is that Democrats need to appeal to conservatives in those red states, not moderates. They already win moderates by a wide margin.
So you not see how you're exactly thinking in stereotypes when you've convinced yourselves that Democrats are winning only due to appealing to this imaginary mass of super liberals instead of actually having a broad based coalition as the polling results show?
That's not a logical way of evaluating the election results. A state being won by only a few points for Republicans in an election they lost by a few points the other way isn't indicative of moderation, it's indicative of a conservative state. (remember, presidential elections only generally swing a few points each way per year)
Can you look at the exit poll results above and explain how your argument makes any sense, given the facts? By the way I think the way some of the people in this thread have attacked you unreasonably and irrationally. That's what people on here do when you disagree with them generally, I've found. That being said, I can't see any way your hypothesis matches up with what the data says.
