Marco Rubio doesn’t like his day job.

Too bad. He ought to quit and concentrate on the other job he is seeking.

He’s a United States senator from Florida seeking to become president of the United States.

Rubio told the Washington Post that the Senate frustrates him. His friends and close associates say he “hates” the Senate. It’s too slow. Too bound by procedure. Too this and too that. Rubio is a young man on the move and he wants a job that will enable him to get things done in a hurry.

Rubio wants out of a job that pays him a pretty handsome salary, about 175 grand annually. But now that he’s seeking the presidency, he’s been off the Senate grid for most of the year.

His Senate absenteeism has drawn fire from the home folks. According to the Post: “On the campaign trail, Rubio comes under attack from rivals who say he’s become an absentee federal employee. Former Florida governor Jeb Bush, in a less-than-subtle knock on his former homestate ally, has said senators who miss work should have their pay docked.

“’It’s just, kind of, like, dude, you know, either drop out or do something,’ Bush’s son, Jeb Bush Jr., told New York University College Republicans earlier this month, in comments first reported by Politico Florida. The junior Bush, a Floridian, cast himself as an aggrieved constituent. ‘We’re paying you to do something, it ain’t run for president.’”

I don’t begrudge the Republican senator for wanting to seek higher office. I’ve noted already that other senators have done the same thing.

But the way I see it, if Rubio dislikes the job he has so much that he’s willing to admit it publicly, then perhaps it’s time for him to quit that job., let the governor of his state appoint a suitable successor — who’ll do the job and actually earn that six-figure salary — and then devote all his waking-hours energy to seeking that White House gig.

Rubio already has declared he won’t seek re-election to the Senate next year. He’s decided one term is enough.

Here, though, is a bit of history that Rubio should consider.

In the event he gets elected president next year, he’s likely to find that the presidency is hamstrung as well by certain processes. An anecdotal story has been bandied about Washington for the past 50-plus year about how another young, go-go senator got elected president and became frustrated that he couldn’t snap his fingers to get things done instantaneously.

President John F. Kennedy learned that his new job tied his hands on occasion and that he had to learn to work through the process. Then again, he hated the Senate, too.

Give up your day job, Marco.
