These polls and that map are all useless, I hope you know that. It doesn't matter who's ahead now, no matter who it says is ahead. Wait until after the nominees are chosen, then you can start going crazy about polls. We should all focus on the nomination polls, not the GE ones.
I'd actually go even farther than you do, and say that, even after the nominations have been decided (which will presumably happen in February), the polls will still not be very useful in predicting who will win and by what margin. Frequently, the race doesn't really crystallize until after the conventions, so we might not have a good indication for another year.
However, leaving aside what the polls tell us about who would win nationally, what about the question of relative strength of the two parties between different states? If, hypothetically, we got a bunch of polls showing the Democrats stronger in Florida than Ohio or stronger in West Virginia than Colorado, then might that not tell us something interesting about what the electoral map might look like next year, depending on what the overall national popular vote margin is (which we won't be able to guess for a long time yet)?
