I'm not sure the thought-density is as high as the lexical density. Translating and abridging it to commonspeak:

"My opponents say that federal control of slavery is unconstitutional. While the supreme court previously referenced the 5th amendment's protection of property, Douglas and his adherents point to the 10th, which grants powers to the states whenever not granted to the federal government."

The first two sentences are completely unnecessary.
