Hindsight

One advantage a presidential candidate has against an incumbent is hindsight. It's very easy for any candidate to explain a situation and criticize the President, and then say, "I would have done it differently." That's because no one can disprove or refute your statement.

All the while the President has a record. The truth is that whatever the candidate says in these situations is a lie, because they don't really know what they would have done given the situation, conditions, facts and views presented to them at the time a decision needed to be made.

They don't really know, but it's always easy to say something in hindsight. Something we should all remember when we hear a presidental candidate say, "I would have done it differently?" They don't know anymore than we do or would.
