The reason everyone obsesses over the wants & needs of moderates is bc they r constantly threatening to vote for the other team/stay home. The party thinks the left will vote for them no matter what so we have 0 power & get treated like crap.
That’s why even though M4A and GND are overwhelmingly popular, voters choose Biden because they believe they must appease those finicky moderates. Progressives and leftists can be endlessly shit on (compared to nazis called toxic etc) bc they assume we will still vote blue anyway
