FB already stated they will allow disinformation

How would Bern stop that?

I read a story that Twitter is going to a ratings of political statements truth

If the platforms allow it...how does a candidate stop It?

Maybe when he's POTUS

Are people deciding who to vote for based on online exchanges?

...you would think the party that lost in large part to the disinformation in 2016 would be out in front of this, and/or actively combating the problem...

Instead of perpetuating the trope.
