Hillary Clinton is popular among Democrats, that is certainly true. This argument overlooks the fact that:
a.) Hillary Clinton nearly beat Barack Obama (one of the most popular presidential candidates in modern times) in one of the closest primary elections in history. That in and of itself does speak volumes about her capability to run a tough campaign.
and
b.) Comparing the Bushes and the Clinton's is a false dichotomy. It's like comparing broccoli and apples. The Clinton's are not a "dynasty" in the way that the Bushes are, with multiple people from the same family seeking the presidency. Hillary Clinton is related to Bill Clinton through marriage and has significant accomplishments in her own right -- comparing her to Jeb Bush is incredibly narrow minded.
This article is not advocating one way or another of what Hillary should do. Rather, it is discussing the possibility that she could run for president again, and if she did, it would not be unprecedented, and she has every right to do so.
