Incest in Mississippi

The New York Times printed a list of what states had what bans on abortion.  Twelve states have complete bans on abortions with no exceptions for rape or incest.  A number of states, like West Virginia, have banned abortions but had exceptions for rape and incest.

Then we get to Mississippi.  In Mississippi abortion is banned with exceptions for rape, but not incest.  I think that is really strange.
