What's more, most internal campaign polling isn't really about the head-to-head, anyway; it's about how to deploy messages, and what groups to pitch those messages to. Yes, presidential campaigns (and to a lesser extent statewide campaigns) do have to make decisions about where to move resources. But that's generally not the big decision they have to make. If that's all there was, I'm not even sure that presidential candidates would find it worthwhile to poll at all.
The flip side of this is that the campaigns absolutely should be spinning all of it as much as they can. Losing campaigns need to keep their supporters fired up; winning ones want to prevent complacency. Neither side wants the other to dominate the information environment, on the polls or anything else. So, yes, you can expect the spin to continue, and even be upset with your side if they aren't doing it. Just don't pay any attention to what they're saying.
