Even in the 15th and final finale of “American Idol,” it was tough to beat Kelly Clarkson.

Many have said, with a regularity that borders on mania, that no other winner embodies the inner grit, eternal enthusiasm and musical passion of the “American Idol” ethos better than Clarkson, and Thursday night’s medley offered final and fabulous proof.

Which is pretty much “American Idol” in a nutshell: Sing big, own your brand and leverage social media.

Even for those of who stopped watching “Idol” years ago, the finale was worth watching for Clarkson alone.

Opening with President Obama’s masterful pivot from the importance of “Idol” to the importance of voting in November, the finale was essentially “American Idol’s Greatest Hits,” two hours filled with strong and varied performances from stellar fan favorites, from Pia Toscano and Jordin Sparks to the goofy “Pants on the ground guy” and William Huang.

As Clarkson proved, though the due date is near, the original can still bring it.
