You could argue that people who are more sensitive to this issue in 2016 are also more likely to reconsider whether a woman should be blamed for her husband's failings.While that is true, my reading of the current times is that there are now more Republican-leaners who would consider that a bad thing (in the 90s, this seemed to be limited to mostly overly-religious puritan types who gave a shit about this on a personal level). There are also more Democratic-leaners who are turned off more about this, enough that it might consider them to second guess Hillary.
I'm not really thinking about the die-hards. Their minds are already made up. I'm trying to visualize the people who are on the edge of being persuaded either way.
It's hard to tell the effect unless the news item picks up steam and hangs in the news for a few days while pollsters do their things.
