“People like bipartisanship not because they like the substance of what bipartisanship produces, but because it reduces the cognitive stress that partisan disagreement creates. If two sides are bitterly arguing over some major piece of public policy, this forces us to choose sides, and for those with weak mastery of the issue or tenuous connections to a specific worldview, it is easy to be stalked by the worry that you’re choosing the wrong side: After all, there are a ton of people screaming in righteous indignation that the side you’re on is about to destroy the country.”
