That is why suburban women especially seem to have gone against Trump. His supporters in that family centric demographic now decline even more to participate in polls, which thus makes the available survey respondents less friendly toward Trump.
Pollsters are hard put to identify and correct for this effect. Their demographic and turnout models are thus of doubtful reliability. This makes the polls increasingly unreliable except to show relative changes, which now indicate that Trump is surging.
The best way, IMHO, is asking, Who do you think will win?
The Trump voter can answer that without taking responsibility for the prediction.
That works, to a degree, but it still fails to get people into the survey who simply do not answer surveys or calls from unrecognized numbers.
