As the world watches Donald Trump build a presidential administration, it is good to wonder: Who among these senior officials is going to have a lick of influence on the guy who selected them?

I ask as reports today tell us that Sen. “Little Marco” Rubio will get the nod as secretary of state. Rubio once was a ferocious critic of the next president. He ran against him for the 2016 Republican Party presidential nomination. He drew plenty of fire from Trump, who labeled him “Little Marco” in a successful effort to knock him down to size.

Marco Rubio also used to be a fierce hawk against Russia, against North Korea, China and once called for comprehensive immigration reform.

Hmm. Where is this going? Trump wants to make nice with Russia, likely seeks to resume the romantic correspondence with Kim Jong Un and will have nothing to do with reforming our national immigration policy.

The question of the moment is this: How will Little Marco be able to influence the POTUS on anything? Which one of these Rubio incarnations will show up for work, will testify before the Senate Foreign Relations Committee during his confirmation hearing? For that matter, how will any of the individuals Trump has chosen affect decisions that are coming down the road?

I will say this about Rubio. He is qualified to be secretary of state. He served for many years in the Senate and has shown a level of expertise on foreign policy that the new administration will need.

The question, though, remains the same. Will any of that experience and moxey matter when the new president faces critical mass at decision time?
