As a British citizen but follower of American politics, I was a ardent supporter of Hillary Clinton in 2016. Like you, I believe the female is future and and a woman president would have been beneficial for the whole world to aspire to.
However, I am a hard left socialist and oppose Clinton’s neoliberal agenda. She’s too centrist for me but I still would choose her over any Republican.
I never believed that Hillary should run again after the disaster that was 2 years ago. But you have made a strong case for it. If Hillary was to run again, and no suitable socialist was against her in the primaries, i would now back her after reading this article!
