How did Amash spin his NAY vote? Did he say that it exceeded Congress’s ennumerated powers, à la Ron Paul? (Then again, didn’t Paul vote for the bill?)
However, the legislation is not a mandate--it supports and encourages the display of the motto in all public buildings, schools, government installations, etc. It also seems to make it more difficult for atheistic whack jobs to call for, and be granted, removal of the motto. Sure, it's relatively meaningless legislation, but to me it's a sway in the right direction.
