Republicans are moving in that direction in larger numbers all the time. That trend will continue, I think, right up to the election.

Other Republicans, mostly moderates, will vote for Clinton, although they may not tell pollsters that in large numbers. In many households, women who are moderate Republicans will vote for Hillary, despite the men in the household telling poll-takers that their household will vote for Trump.

That's what I think, anyhow. I suspect her lead is actually stronger than the polls indicate.
