Was Trump’s surprise and stunning victory more attributed to those who did not get out and vote for Hilary, those that did not help her by writing in Sanders or others, or she was plain not good enough to be elected?

If some thought her like Teflon, could not be beat so they did not get to the polls to vote, is that not like a de facto vote for Trump? Likewise, those that did get out and vote but cast a ballot for Sanders, Mickey Mouse, etc. out of protest, did they not by default help Trump? Hilary had two bites at this cherry and came out with a pit each time, is it just she just don’t have what it takes to be elected to the High Office, even against someone who never held and office of any sort, not even on the school board?
