The Republican primary contest was already close enough to being “American Idol.”

End it on a high note? Yes. Literally — as Cain did at the National Press Club on Monday.

Cain sings pretty well for a GOP presidential candidate. I realize that this is like saying, “You can beat-box pretty well for a Founding Father,” or “You know an acceptable amount about foreign policy for a pizza CEO,” but we have to work with what we’re given.

Say what you will about Herman Cain (“This sexual harassment scandal isn’t going away as quickly as it Cain hoped it would!” “And what about that campaign finance thing?”), but the man has a certain amount of aplomb and an unprecedented ability to burst into song. If Abraham Lincoln had done this back in his presidential candidate days — well, he might not have been elected, come to think of it. But it’s still worth trying!

And it’s by far the best way to end tense afternoons of questioning.

“Any closing statements for this debate?”

Cue the orchestra.

After all, Rick Perry has already demonstrated that, with passion, he can be a pretty fun guy. Maybe he knows a few tunes. Mitt Romney can sing “Baby I Will Wait For You“ to tepid applause.

Ron Paul can sing “Silver and Gold.” Rick Santorum can perform a stirring rendition of “Mr. Cellophane.” Michele Bachmann can sing “And I Am Telling You I’m Not Going.” So can Newt.

Huntsman can sing, “It’s Not Easy Being Green,” or some hipster song by a band that nobody has heard of yet.

They say that if people around you suddenly begin bursting into song, either you’re trapped in a musical or you’ve finally cracked. Given the state of things these days, it seems likely that it’s the latter. But the former would be a lot more fun.
