I think there are two ways of looking at this song. The idiomatic is using American street slang to say “stop talking, get rid of the problem, it’s time to do something” while the literal refers to the problem of guns control by mentioning the “Get the lead out of schools” bill and opposing the “gun up buttercup” slogan. When you put them together, there’s a clear message calling to resolve the guns problem now.
