Do you imagine a Mars colony will not have its own politics? Politics is arguably motivated in large part by scarcity. On Mars resources are a lot harder to come by than on Earth.

You could make an argument that a shared struggle against extreme conditions would stabilize societies and make cooperation a necessity, but a Mars colony is going to need a lot of help from Earth to get on its feet, in which case we still need to solve terrestrial politics anyway.

A Mars colony would be small by necessity. Everyone will know everyone else. In such communities "politics" is not nearly so abstract. For instance, you can't convince yourself that climate change is not happening when you personally know the experts in that field taking the measurements and crunching the data. There will always be disagreements but nowhere near the type of nonsense we see here on Earth.
