Who is?  Ms. Clinton?  She's still making excuses for what was thought to be a sure win.  It's about her ego now and trying to spin everything to gain sympathy support.  "I am very aware of, you know, the challenges, the problems, the shortfalls that WE had."  She isn't apologising for her mistakes and lack of leadership, but everyone as a party, it's already been analysed to death.  If she has some proof she should come forward instead of relying on speculation. 

The writer?  She's trying to put a spin on something for feminism.  Ms. Clinton lost to an upstart named Barrack Obama, was that sexism in play?  She would've lost to Bernie Sanders had the Dems not interfered in the process.  Still sexism?  Using Ms. Fontaine as an example is odd also considering how the PCs accused her of covering up sexism at the Manitoba Legislature and how she refused to apologise for these actions.  My guess is the writer wishes to use these articles for future reference instead of relying on fact.
