That's all well and good, but can you show me where Trump "attacked" the Khan family?
I think the argument is that while he expressed appreciation for the family's sacrifice and their son's service (calling him a hero), he was inappropriate when he flippantly stated that he's like to hear from his wife. It sure seemed like Trump was taking a jab at Muslims for not letting their women talk.
This is rude, albeit confusing for a liberal to defend. You can pretend Muslims are whatever you want them to be, but women have far less rights and privileges in many Muslim countries.
Also, it's a little inconsistent that they don't get on Hilary for implying that the Benghazi families are either mis-remembering, lying, or political, when the Judical Watch e-mails confirmed that their story corresponded to the facts: i.e., we all know for a fact that the State Department was blaming the incident on the tape after confirming it knew that the tape had nothing to do with it. So the victim's familiies should have been vindicated. However, she's still pushing the story, like she's pushing the "I didn't lie about the e-mails" story.
3. He starts to pack it in and complains about how the process is rigged and he isn't being treated fairly, etc. Railing against the system would be his way of not accepting any responsibility for losing. I don't see him going this way completely yet, but if after a debate or two he is still down a fair amount, I think he will go this way to protect his ego.
While I have no doubt Trump is his own worst enemy in the election, more and more people are starting to think the system is rigged.
1) The FBI gave Repubs a lot of reason to think it is.
2) The DNC gave the Bernie people a lot of reason to think it is.
So when trump talks about rigged elections, and someone says that's crazy, and look at him for his crazy answer and he says
"There is no ID requirement like there is in EVERY other aspect of modern life! Why would you lift an ID requirement if you didn't want to cheat?"
Guess what? No matter how crazy you think Trump is, that just doesn't sound very crazy at all. It just doesn't. People have their responses, but they are weak and don't get past the problem that--just or not--the no ID thing creates an opening for cheating. No ID, no purple fingers, nothing. Just sign the affidavit. Combine that with mail-in voting... It is an honor system in a country that doesn't believe in honor anymore.
So people who are primed to distrust the system are going to, and they aren't going to think they are being crazy or absurd.
And when the response is "That's crazy, the EXPERTS have shown us that there is no substantial cheating going on." People aren't going to buy that anymore.
I have no reason, personally, to think any large scale cheating is going on, but I certainly wouldn't be shocked to find out, say, Philadelphia or a few key Ohio suburbs were cheating. I know first hand that state-level cheating was rampant in Alabama even 10 years ago.
