With respect to you and this poll, the answer is this: for any of these to turn blue in a presidential election, we would see a Democrat elected having carried 80 percent of the states in this country. An overwhelming, national victory like what we used to get before the 1990s. (My answer is the same with the other thread's poll, touching on the same subject but asking for a scenario opposite of this one.)
So, if I understand you right, to paraphrase, your response would be:
never, except for a Democratic landslide victory?
