On the correct Usage of word "jackshit."

[raccoon]

For example, if I am saying that a public figure doesn’t know anything about a subject. Which is correct:

1. The Dotard knows jackshit about medicine.

2. The Dotard doesn’t know jackshit about medicine.

Now it seems to me that the second choice can be construed as a double negative. The word itself, jackshit, refers to nothing. If I add in the word “doesn’t”, that seems to be a double negative.

What do you think?
