This is typical of the nonsense Republicans waste time doing when they're in power, and the nonsense the Democrats are too afraid to put a stop to. It's the same way that they unnamed our national airport from George Washington to Ronald Reagan. You'd think a Democrat could find a way to defend, and win, again an attack on George Washington. You'd think wrong. Our airport is now named after Reagan, though no one calls it that. So now we're going to spend possibly $100m or more chiseling 'In God We Trust" all over every federal, because that's the reason divorce is at 50%, our violent crime rate is far too high for a developed country, our infant health figures are far too low, and we pay twice as much as any developed country (with far less return on our money) for health care - all because no one had thought of chiseling "In God We Trust" on a 9,000 buildings.

What an absurd waste of money. It would be like renaming various public schools JFK or RFK High School.
I think they're trying to make a point more than anything. "In God We Trust" is printed on our money.
