You are correct Sniper, but without the government being involved none of these projects could ever get off the ground. The scope of most of these projects is to large for anything other than the federal government. And as with the interstate highway system, a new power grid could and probably would be built by private contractors.
As far as blowing money on pet projects, I am pretty sure I heard Obama talk about rebuilding our nations infrastructure. This sounds like a perfect project to get started rebuilding, and doesn't sound like a waste of money to me.
I believe that these particular churches are getting nervous that the government might soon actually begin investigating the tax exempt status of churches in general.
