I know this is crass but will he even be around by then?
This is a major concern of mine. In four years Bernie will be 79 (which is the US life expectancy). We need someone who represents a new generation and the new Democratic Party, not just one.
But if he does get the nomination, he'd better pick a good VP. It will be important.
This.
For some reason, both parties nominated olds. I frankly questioned how likely it was that either candidate to survive this terms (and I liked Pence more than Kaine).
When my father was my age, he was roughly the same age as the incumbent President. In this election, both candidates were old enough to be my parents (though Hillary would have been a teenage mother).
