re: Lawfare: how is this defined, and how can it be (legally) stopped?

One of the things I see not presented is just the intent to cow opponents into submission with the threat of bankrupting them or diluting their efforts via lawsuits.

When you have a cadre of Soros-type mega millionaires with a political agenda, they can hire legions of lawyers to tie you up in court until you submit or obey.

I think a lot of the current Trump attacks are motivated by "at least we can keep him in court - generating hours of bad publicity via our allies in the media. If we get a good verdict, that is just icing on the cake."
