Care to explain the difference?  I think this conversation is awfully 
close to bordering on semantics.  So I suppose a definition of 
electrical current and ionic current is in order.  I think we all agree 
that ionic current can simply be characterized as the net flow of charge 
  due to translational motion of ions.  So is "electrical current" that 
current due to electron flow only, or can it be characterized simply by 
net flow of charge?
