Why is Trump rebounding slowly?

[Fmr. Pres. Duke]

The Khan fiasco hurt him a lot given he was actually tied or ahead in most polls prior.

His new campaign team seems to be keeping him on a shorter leash, and he's strangely pivoting to make his positions seem not as crazy, not that I believe Trump has any actual policy planks.

The advantage he has is Hillary is really unlikeable and there are plenty of people supporting her because they feel like there is no other option. I think Trump will continue to pull closer until he makes another gaffe, but who knows.

We may not see much movement in the polls until the first debate.
