American candidates

So, it would seem Bernie's health rules him out, and the Democratic candidate for President will be Biden or Warren.

I really don't follow American politics in the same level of detail that other people do, so I haven't paid much attention to Warren.  But Biden does seem too old and past it, and while Warren herself is 70, she looks younger and pretty fit.  She seems a lot younger than Trump, even though he is only 3 years older.    

Lots of people I trust on twitter say she's good at explaining stuff, and Zuckerberg has it in for her, so she probably should be the next President.   She is said to have Wall Street in a panic because she wants a wealth tax (but only kicks in at $50 million)  Surely Democrats can stand up to the rich who think that will be a disaster?

Americans can be a bit weird in their view of tax though.  They fantasise about upward mobility so much that they can imagine how annoyed they would be if facing a wealth tax, even if they're personally forever stuck on a barely living wage and have so few assets that urgent health care could send them bankrupt.
