When Barack Obama exits the office of the Presidency on January 20, 2017 he will live in a home in Washington D.C. Unlike previous presidents who go back to their home states living is self chosen obscurity as not to conflict with the current President in respect of Office and its challenging position.
Well Barack Obama most likely chose to live in Washington D.C. so he can support the Democratic president or criticize the Republican President. I think the Democratic President may like some support yet rather have it quietly over a phone call not in public. Similarly but opposite I think the Republican President would not like a former opposing party president commenting on current issue being dealt with and raising the ire of the public against his every decision.
Now if Barack Obama was morally sound and pro-America and Donald Trump morally suspect and Anti-American Barack would be commenting from the high-ground. Yet, Barack Obama is caught up in his Colonialist, Socialist Idealism nothing anyone has said during his presidency or will say after that will make any of his positions Pro-American. Its hard to believe that every single decision he has made is Anti-American, or some would say he hates American, ergo Colonialist.
So what can a Republican President do to deal with such a dissenting voice? He can have a private conversation telling the former president, “Remember all those scandals you blocked investigation on so you could get Hillary Clinton get elected and looked above all the fray. Well, I am going to have my Attorney General prosecute all your underlings and yourself until you are comfortably in prison. So do you want to avoid all the prosecution or not? Keep in mind that does not mean I will not prosecute anything. Some criminal activities the public has a right to know. Since you are not going to respect the office of the presidency like all previous presidents I am not going to let you get away with all the crimes you have committed.
