separation of church and state

As I was reading this post:

While I took out my voter registration card and driver's license, I noticed to my right that the authorities hadn't cleansed the place of other appeals to voters' consciences and intentions. As large as life there was Jesus, in plaster, hands outstretched nearly in my direction. I could see the print of the nails. His Sacred Heart stood bare for all to see.

I realized that every time I have voted, it has been in a church. I guess the government needs religious buildings, just not religious thought.
