Like PPP, ARG finds Romney with a double digit lead amongst Independent voters. Romney leads 55-40% w/ Indys per ARG, and 54-36% w/ Indys PPP. One of the reasons PPP has it tied and ARG ROmney +4 is that PPP's survey showed voters party ID to be D+14, while ARG finds it to be D+10.
How many times to people have to say that party ID changes and is not immutable. Party ID is not like race/sex/age, it is more like presidential approval. There are two possibilities:
A. The polls are tracking a shift following DNC and 47%.
B. The polls suddenly flawed in the last month (and possibly part of a conspiracy).
As for NC, it is still amazing that this state is still in play. Romney was supposed to have this state locked down like MO and IN by his convention.
