Those comments will have zero impact on President Trump’s support because (1) most of his supporters are unaware that he said them, (2) most of the rest don’t care, (3) many of them think “she’s not my type” is a relevant and appropriate argument in establishing one’s defense in a rape accusation, and (4) they believe an exit strategy is unnecessary because we would, in President Trump’s words, obliterate them.
After all, they might ask, did we need an exit strategy as we marched into Nazi Germany? Of course, even those with a cursory knowledge of history knows we did need an exit strategy.

I would be happy to eat crow on this matter, but I am pretty certain that if the support numbers have not shifted in the past two years, we are not going to have one in the next two years.
