Who defines what voting well is? Or what a good party is?

The observed damage that the UK has inflicted to itself has been caused so far by all the parties that have been in power.

Voting in ways that genuinely serve their interests, perhaps?

Voting in an educated manner?

Voting for candidates and policies that will help people overall, rather than those that will hurt people overall, just so that they can hurt Those People?

Those seem to be the major differences alright. Well put.
