"Failure" is a determination that's always made in the present tense.  And it's based on the accumulation of more-quotidian successes and/or failures up to that moment, the sum totaling of the evidence, if you will.  

If we look at Admin 45 three months in, what kind of track record do we observe, if not flailing upon flailing, failure upon failure?  The "successes" he claims were, almost without exception, set in motion prior to his claiming the Oval Office.  By those metrics indeed he has already failed.
