There’s a more practical political consideration regarding impeachment: there are 54 Republicans in the Senate, including the RINOs. It takes 67 votes to convict and remove him from office.
Ten Republicans voted Clinton not guilty of perjury and five Republicans voted him not guilty of obstruction of justice. The final votes were 55-45 not guilty of perjury and 50-50 not guilty of obstruction.
Obama is likely be found not guilty without at least 13 Democrat guilty votes and that’s unlikely. The Republicans then would have handed Obama a major political victory if impeachment failed to convict.
Clinton’s job approval ratings skyrocketed after the failed impeachment trial and the Republicans looked like losers. We wouldn’t have Clinton’s wife running for president today if he had been found guilty.
In my humble opinion, the best way to get rid of Obama is via a grand jury investigation and criminal indictments being handed down by a prosecutor that would be so embarrassing that the DNC would ask for him to resign for the sake of the party.
