A lot of factors came together to make Trump President. Many of them were beyond Hillary's control, but some were well within her ability to influence. What appears to be a stubborn refusal to recognize that if she had made one or two different (and arguably better) choices, she would be President today instead of the Orange Offal is rather frustrating and disappointing.
With as close as the election was, there could be many things she could have done differently that would have led to a different outcome. Hindsight is 20/20. And just because she could have won with some changes, it doesn't mean they were the best choice at the time. Imagine if she had spent a bunch of time in the last 2 weeks in PA/MI/WI, and won them easily, only to barely lose Colorado.
I'm sure you have other things in mind. But the same principle applies. Whatever she might have done differently, there could have been unexpected consequences that ended up hurting her more.
Regardless of what she could have done to win, it doesn't obviate the significance of any external factors that affected the race, especially if there were illegalities in play, as she implying.
If your issue is just that she should own up to mistakes, well ok, she did say the campaign wasn't perfect. Maybe that's not definitive enough for your liking. But then, if the election was essentially stolen, I think that's more significant than any alterations she could have made that *might* have resulted in her winning.
