The whole idea of a Constitutional Republic is to prevent the "tyranny of the majority." The "tyranny of the majority" has another name: democracy. The founders knew all about the Greek City States who had democracy, which always went down in flame at the hands of demagogic tyrants. So why, starting in the 1930's did the Government, and notably the Government run schools, start referring to our form of government as a democracy, or maybe a "democratic republic"? I'll leave that to the readers to figure out.
