It's hard to imagine a world where Clinton is up ~7 points nationally, and up 1 in CO or up only 5 in WI. And I don't think you can really blame RV/LV split, because from what we've seen from polls that have given us both RV and LV results, there is little-to-no Repub LV advantage this year.
I know she's not a great fit for CO, but neither is Trump. We have seen Dems well overperform their polling in CO and NV, so that could be going on.
You guys are forgetting the MoE: Clinton could be leading by 9 in WI right now (which is what Marquette showed). I think she's eventually favoured in CO as well (it usually underpolls for the Dem. candidate). But in general, all these state polls recently match up with a 5-6% national lead ... and not a 12-point lead (like that garbage WaPo poll says).
