Axios has some interesting stats:

• About 27% of U.S. adults report not be affiliated with any religion. Only 4% of our elected officials will admit to the same? This implies to me that organized religion is…well…organized when it comes to pushing its priorities in the public realm.
• 90% of Congress members identify as Christian, compared to 65% of the population. About 6% of Congress is Jewish compared to 2% of the population, so they are overrepresented. If you round to the nearest percent, “Buddhists or Hindus” and Muslims each make up around 1% of the population, and around 1% of Congress. If you talk to Buddhists AND Hindus, they might have some thoughts on how they have been lumped together in this survey.

So, I suppose the U.S. is still a majority Christian nation, and certainly a majority religious nation, but the viewpoints of nearly a third of us are severely underrepresented by our elected leaders.

This survey did not address how many of our elected leaders who claim to be religious humans are actually lizards who drink the blood of human babies in the basements of pizza parlors.
