Respectable opinion takes it for granted that you can't have too much politics.
The model citizen of a healthy democratic nation is above all "engaged" -- informed, with strongly held views that he or she advances at every opportunity. Less politics means a passive, apathetic electorate. More politics must be good.
The United States, if you ask me, casts doubt on this.
Here is a country divided. The split is not just between Democrats and Republicans, between center-left and hard right. The United States is also divided between a political class and an apolitical class.
On one side, opinion shapers, policymakers and party disciples, engaged to the fullest -- on the other, the bored and disenchanted, who've looked at the deeply committed and given up on Washington and all its works.
Here's the point, though: The sickness in U.S. democracy lies less with the disengaged, whose boredom is forgivable, than with the model citizens who are all politics all the time.
American politics goes beyond Congress and the White House. The civil service is also thoroughly politicized. Political appointees go several layers down across every agency of the executive branch. Even U.S. courts are politicized.
Today, the highest court in the land -- four conservatives, four liberals and a swing vote -- is expected to pronounce on the design of the country's health care system.
