Other ways as well. Some Dems have even admitted it, and are downplaying it instead of denying it (e.g., Ro Khanna, who is not a bad dude IMO). They have passed beyond the "it isn't happening" stage to the "ok, it's happening, but its no big deal" stage.
Granted, some Dems raised their hands on stage during the Dem primary debates to go further and say it is a good idea.
Where do you stand? Do you think it's a good idea like Biden & Harris?
