Should Mr. obama come back to the white house for another four years.?

Mr. Obama should come back to testify under oath what he knew about the spying on the Trump campaign and when he knew it. There are FBI emails indicating that the White House wanted to be kept informed about what was happening.

No.  8 years of a novelty President was enough!

Should we have a smooth talker in the White House that gets nothing done, or someone that may not speak as well, but wants to help our country and make it great again?

No  He  is the worst President ever  and did enough   corruption and  damage ,Does  He want to spy  some more??

He can't. And there is no "should" in politics. 

Why? Did the current janitor retire?

He can't even if he wanted to.  Lifetime term limits, you know.

Only if he wants to be arrested for trespassing 

obama has done enough damage to America.

Maybe just for one to babysit Trump until we get a real president.
