It's not that easy. The deeper issue is plurality voting and duverger's law, with people being incentivized not to vote for something but to vote against a perceived evil, as that's what the campaigns get more traction with on the whole.

Plurality voting applied to the tragedy of the commons, i.e. the nash equilibrium decision matrix, results in the worst possibility if there's no basis for trust. If we could vote on the results of that matrix, by replacing {+1, 0, 0, 0...} voting with {+1, +0.5, -0.5, 0, 0, 0...} voting, things might actually improve with 3-4 viable, local parties, with smart selection of candidates actually representing districts constructively and campaigning accordingly.

But we don't have that. I fear its absence at all scales from local right on up to resolution of international conflict may end up being the Great Filter: The coordination problem of solving the tragedy of the commons in all its forms.
