Exactly, which is why this professor is complete full of "Democrat platform" (see Reagan joke).
Any change to a term limit will not have an effect on the current incumbent. Period.
The two-term limit set as a result of FDR during Truman's presidency didn't affect Truman, but it affected Eisenhower and later. This professor is so completely ignorant as to boggle the mind.
I think what is intended here is a Constitutional amendment that would be retroactive, and apply to 0bama, and only 0. Probably specify that while each of the first two terms are 4years each, the third is a life term.
