If he continues like he has for the past few days he can't win, if he sticks to some substance which he has today as of now, he can rebound and win
How many times have we thought Trump was finished during this election cycle? I am never going to say he's done again until he actually loses to Hillary.
I highlighted one part of a sentence. Anyone who's had a child with behavioral health issues knows what it's like to go one day at a time, or a half a day at a time, hoping that, yes, he/she can really get through the school year OK. Often, it's disappointing, and the child grows to adulthood still needing remediation of some sort.
Trump is getting to the point where I wonder about this. A candidate that has "good days" and "bad days"? For President? Americans want some consistency in their President; a smidgen of a-hole is tolerable, and (sometimes) desirable, but it's not OK as the norm. If a "mental health" narrative grips Trump's campaign, the entire GOP will have to bail on him. I'm not saying Trump's there, yet, but I am amazed at the inability he has to take critical feedback, even from friends and family. That's not good at all.
