Lame-duck U.S. Sen. Bob Corker, R-Tenn., says he “might vote” for a Democrat for president in 2020.

To which I say: Big . . . bleeping . . . deal!

Does it really matter one bit what a U.S. senator might do when he gets a chance in a couple of years to vote — in private! — for the candidate of his choice?

No it doesn’t.

I grow weary of hearing from these politicians who believe that expressing their voting preferences in public somehow gives their ballot-casting some added significance, some gravitas.

Corker is a fine man. He announced about a year ago that he wouldn’t run for re-election to the Senate from Tennessee. That’s when he grew a pair of ’em and started speaking out against the president of his own party. If only he had been as stern prior to his becoming a lame duck. But . . . whatever.

Now he says he might vote for a Democrat.

The founders made sure we could vote in private for a reason. It was to protect citizens against recrimination, coercion and pressure. Sure, I occasionally reveal my own voting preferences on this blog. I also know that it doesn’t mean anything to damn near anyone because readers of this blog have their minds made up already; I just choose to use this forum to vent.

So, to Sen. Corker I only want to add, feel free to vote for whomever you choose, sir. You are entitled to write in The Man in the Moon if that’s your choice. You’re under no obligation to tell us about it.

Indeed, I care about that as much as I care about knowing you might cast your ballot for a Democrat next time around.
