Nonsense. If Hillary wins, Obama will pardon her whole crew anyway. The Dems must be terrified of Trump winning, in which case the Hillary trial continues unabated and then their party really gets dragged through the mud like we did with Nixon.
We didn’t need 20 years to get back in the White House after Nixon either.
Pardons do not affect impeachments.
A removal from office can still go forward.
Obama can pardon the Clintons for criminal activity, but no Presidential pardon can keep her from being impeached while she is in office.
The only way to prevent the impeachment trial is to keep her from winning next week. The only way to keep the dirty laundry safely in the hamper is to prevent an impeachment trial.
