New Fox News poll that is pretty much post-Khan has Trump down 10% in a straight up against Hillary, and down 9% all the way back at 35% in the three way (nice bump for Gary Johnson to 12%). Every single group disapproves of his Khan handling, and only "Republicans" are even close to a split at 41/40 disapprove. This single event may not cost him the election, but it shows that his inability to check himself over the next 3 months leaves him little hope. Also the questions about temperament, qualification and knowledge to be President give overwhelming advantages to Hillary

Univision Florida poll shows just how difficult Trump's path to winning is: He's only getting 13% of the Latino vote. Even if that doubles nationwide, he's well behind Romney who obviously lost handily. It is an online poll, but even if you wanna apply a 150% margin of error that still puts Trump well behind Romney's pace with Latinos.

Also strongly working against Trump is Obama's net approval might hit double digit positive if the trends continue. Almost all pollsters have him with a high single digit net approval. With Obama likely to be a crucial campaign weapon, he's even more devastating to Trump with strong numbers.
