What should the Dems plan of attack be for 2020?

Opposed voter suppression and sought to increase and ease voter registration and access, I must conclude from all the exchanges on the subject.

In the US paradigm, yes

Of course there is Europe in an alternative world; Germany is at full capacity with full employment, for example. The Mediterranean countries have had serious post-2008 problems but haven’t lost jobs to globalisation.

Globalisation is a bogus argument. It’s about corporate profiteering supported by a bribed political class who sold US workers down the river for more campaign donations.

Early voting, same day registration… None of these things were considered particularly necessary until Democrats started losing elections due to turnout problems. When turnout was low but affected both parties equally, Democrats had no particular interest in figuring out how to get more people voting.
