But you only have 2 parties. If you vote for the party that over spends less you show that this is an election winning strategy and will influence governing more.
U popular opinion for sure, and I'm not even saying it as my view today, but there is argument to be made that we don't own anyone a vote and if both parties are terrible options we can walk away and engage elsewhere. If I really believed both parties were bad options, I'd focus on working with my local community as much as possible. If the federal government can't represent me in anyway then I'd be walking out of that system as much as possible.
