Actually, saving the worst until just right before the election could be interpreted as saying 'hey I did my job and didn't wait until after' while still ensuring that any investigation and finding would not happen until someone with a pretty safe lead is elected.
Career government officials are not likely to be activist about investigations. As with Clinton's denials, which are very passive and "I didn't know" or didn't question something, one can cover oneself very well by simply not offering anything or refusing to ask for something. Sins of omission are much harder to prosecute.
Not to mention that waiting until after means she controls informally if not formally many of the levers that would be used in the investigation. Can a sitting president be trusted not to interfere in any way possible in an investigation that would take from her her highest life's goal? It gets very muddled.
This ignores the fact that whack-a-mole has almost certainly indeed thwarted other attacks that would have otherwise sailed through. The problem is complex, no doubt, but I think for a civilized society pursuing this individually is almost the only option.
I would agree in general that the left has appropriated and advocates the kind of extreme, life-changing response to perceived enemies that it has accused the right of using. I do think that ultimately there will be backlash against this. The left mentions routinely that it has demographics on its side, but I could just as easily envision them being perceived as having gone too far and being the 'establishment' that people will eventually work to rebel against - though at that point, it may be too late.
I think anyone who is capable of graduating from a college, even a flawed one, as she did, has a hard time portraying themselves as vulnerable. At what point is someone responsible. She even graduated, so she has a degree and can legally state that. While I'm happy to see educational institutions being viewed with more skepticism as to their value, I think her situation is pretty cut and dried. Many of us had the experience of getting out of college and for a number of reasons, like the economy, not being able to find a job in the field and having to find another way.
