They do have ID laws in many parts of Europe. However, ID is free or automatically given out in these countries, voter registration is automatic in many places, and mandatory voting is even a thing in the Netherlands and Belgium I believe.
If we want to model our voting system off of Europe, let's go for it. Make ID's free/automatically give them out, same day voter registration, etc. Then we can also have voter ID. Problem solved!
As for the filibuster, it absolutely needs to be reformed or basically nothing can get done in the Senate, for either party. I don't know about full abolition, but it should certainly be reduced. Would be open to a 55 vote filibuster, reinstatement of the talking filibuster, or the idea that I expressed a couple months ago where a bill passed without the filibuster must be passed again by the next Congress in order to go into law.
I don't really see the problem in that. Are you satisfied with the form of government we have now where nothing can get done except through executive action?
