I am not suggesting that all politicians on one side are good. I am suggesting that ignoring truth and reality as things that matter is a trait with very strong correlations with political party, and shouldn't be generically chalked up to "politicians" in general.

As Asimov said: "When people thought the Earth was flat, they were wrong. When people thought the Earth was spherical, they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together."
