No, we should throw it in the fycking garbage where it belongs. No credible poll is going to find a national electorate that is R+4, self-identified or otherwise.
28-30 Aug, Fox news Clinton +2
Among RV
D 41%, R41%, I 16%, DK 3%
I'm not sure what your point is there...? That seems like a pretty silly poll as well if those numbers are party ID numbers:
registered voters are even more "independent" than likely voters. Presumably the chronic references to "40% of the country being independent" are referring to registered voters as a whole; likely voters have tended to be closer to 30%. To have them at 16% significantly over-represents Democrats and Republicans even when measuring registered voters. However, at least this poll's top-line numbers are in line with aggregate polling overall.
Having an election where party ID is tied is obviously possible (see 2004), albeit not very likely in this particular election. Having an election where the electorate is R+4 after two elections where registration has been D+6/7 in such a polarized political climate is not.
