First off, this does not really tell us when the benchmark for "next President" would take place. This could mean 2012, with the election of a Republican. At the same time, this could also mean in 2016. A "next President" may simply mean a different body, because we do not really count two-term Presidents as two Presidents.
Second, this is a very basic lesson in electoral history. It is highly unlikely that a member of the same party will be able to extend a party's one or two-term score into a third or even fourth term. It is not surprising that people think it is "somewhat likely" that a member of the other party will become the "next President".
