My understanding is that blanket pardons have been ruled to not have any effect for anything that hasn't been adjudicated. You can't be pardoned for something you haven't been convicted of. Also, the states are not the federal government, and just like France cannot tell California not to prosecute and convict someone, i.e. France cannot pardon someone with binding effect on California, neither can the federal government. The states are different governments and federal pardons do not affect state prosecutions.
Thanks!
