It actually is a very important factor in who the best Dem candidate is, BUT
Electability is very hard to actually measure (without doing experiments, i.e. elections, which we cant do without a time machine and a bunch of parallel universes!). General election polling is better than nothing, but its not great this far out. The idea that more moderate candidates are generally more electable has some actual data backing it up, but we dont know for sure that that would hold up in these very polarized times.
So my basic philosophy is to just vote for whoever you think will make the best president in the primary, and then vote for the Dem nominee regardless of who it is in the general. And youll note that Im generally arguing for Biden because I think hed make the best president of the plausible choices, not because I think hes the most electable (which, again, I do, but with high uncertainty).
