After more than a decade, will this be the time when it's restored

According to Kristina Peterson writing in the online edition of the Wall Street Journal on December 25, 2014 (“Calder Sculpture Triggers Heavenly Debate in Washington”), there is a debate going on among U.S. senators over whether the sculpture that fills the atrium of the Hart Senate Office Building– “Mountains and Clouds” fabricated after a design by Alexander Calder— should be restored so that its mobile elements will once again be operational. This situation raises a number of thoughts about the factors that go into making the decision to conserve a work of art. Among them: What has to change for a work to get treatment if it has been left in a damaged condition for more than a decade? If many of the people who will involved in making the decision about appropriating money for its treatment dislike a work, will it have a chance of being treated? Would it make a difference if the work were thought of as being “by Calder” rather than being “after a design by Calder”?
