But data based on a subset has no more statistical validity than the size of the subset. Those larger national polls you are referencing are typically only interviewing Republicans a third of the time. Thus, the Republican-specific results of those polls are only as statistically valid as that smaller subset of Republicans would suggest.
Again, in that context, this is actually a relatively large sample of GOP-only voters.
no, you still don’t get it .not at all ..and I’ve not the patience to splain it to you.
