Holder must believe (or know) these two are anti-Palin and will be able to stir up more false accusations against her.
He might even have a deal with them to do just that.
Or....
Maybe, just maybe, it has nothing to do with Palin
and he realized that overzealous prosecutors denied
these legislators a fair trial.
Perhaps you’d prefer they just rot in jail so as not
to possibly embarrass Sarah?
