Justice McReynolds and the War on Drugs

There was some consistency in the early 20th Century cases where federal power was at times interpreted too narrowly (e.g., the Child Labor Cases) -- it took a while for the war on drugs to be readily accepted. Even Holmes in 1916 stated a federal ban as constitutionally dubious. As seen here, nice and bluntly, some retained doubt into the 1920s. McReynolds might have been an ass, but he had his moments. U.S. v. Miller was pretty well written too.
