Blanket. Up to and including the day it is granted for everything. But she can I believe be named an unindicted co-conspirator while the FBI and Sessions go after everyone else including Bill and Huma. She can also I believe be forced to testify against them since she is under a blanket pardon. So not all unicorns and pixie dust.

She won’t be immune to future lying and obstruction of justice, nor can she plead the 5th for anything prior to the pardon.
The incoming DOJ will have many ways to go after Clinton even if pardoned.
Cannot she also be charged, potentially, for STATE crimes, such as, if NY finds something in the Clinton Foundation, etc.?
