Now that GOP front-runner Donald TrumpDonald John TrumpConservatives express concern over House GOP immigration bill Poll: McSally holds 14-point lead in Arizona GOP Senate primary Trump defends Nielsen amid criticism over family separations MORE has released the names of some of his foreign policy advisers, it's only a matter of time before pundits, reporters and voters start demanding to know whom he intends to pick as his vice presidential running mate.

When politely asked now, Trump responds, "I need to win the nomination first. After that, I'll think about it."

To the untrained eye, this seems like a reasonable answer; however, no insider I know believes The Donald hasn't already begun to create a short list of possible candidates.

Ditto Hillary ClintonHillary Diane Rodham ClintonLewandowski says 'womp womp' at story of young girl being separated from mother at border Giuliani: FBI asked me about tease of a 'surprise' before election Republicans tear into IG finding on Clinton probe MORE. The presumptive Democratic presidential nominee has been around the block too many times not to have several running mates in mind, even if it still is March.

So whom will Trump and Clinton pick? My crystal ball is really fuzzy when it comes to naming running mates. In 2000 and 2004, I urged Democratic nominees Al GoreAlbert (Al) Arnold GoreTwo Norwegian lawmakers nominate Trump for Nobel Peace Prize There’s no need to panic about the rising sea level When it comes to Iran, America is still running the show MORE and John KerryJohn Forbes KerryShould President Trump, like President Obama, forsake human rights in pursuit of the deal with a tyrant? GOP Senate report says Obama officials gave Iran access to US financial system Democrats conflicted over how hard to hit Trump on Iran MORE to name Rep. Zoe Lofgren (D) of San Jose, Calif., to their tickets. Lofgren, who represents Silicon Valley, has been — and still is — a very savvy, battle-tested lawmaker.

Four years ago, I urged Republican nominee Mitt Romney to pick Sen. Lindsey GrahamLindsey Olin GrahamOvernight Health Care — Presented by the Association of American Medical Colleges — Trump officials move to expand non-ObamaCare health plans | 'Zero tolerance' policy stirs fears in health community | New ObamaCare repeal plan McCain, Coons: Trump should withdraw controversial refugee nominee GOP senators drafting legislation to keep immigrant families together MORE (R) of South Carolina. The response I received was quick and candid. The prevailing thought at the time was Graham, a quintessential Washington insider, would be a disaster for Romney.

The day after the 2014 midterm elections, I predicted Ohio Gov. John Kasich and Sen. Dick DurbinRichard (Dick) Joseph DurbinLive coverage: FBI chief, Justice IG testify on critical report Hugh Hewitt to Trump: 'It is 100 percent wrong to separate border-crossing families' Opioid treatment plans must include a trauma-informed approach MORE of Illinois would be the Republican and Democratic running mates in 2016, respectively. Today, every time a reporter asks Kasich if he's interested in the No. 2 position, he laughs hysterically. To my knowledge, no one has asked Durbin what he thinks of my idea.

If there is one thing we have learned from this year's presidential campaign, it's this: The old political playbooks don't seem to apply any longer. Just ask the early supporters of former Republican candidates Jeb Bush, Chris Christie, Scott Walker or Rick Perry. They know what I mean.

The same is true for Bernie SandersBernard (Bernie) SandersHeckler yells ‘Mr. President, f--- you’ as Trump arrives at Capitol Veteran New York Dems face upstart challengers Senate passes 6B defense bill MORE. Who in their right mind could have predicted a year ago that a little-known senator from Vermont would be creating political tidal waves in the Democratic primaries? Surely no one in Camp Clinton thought so.

To many, running for president seems like an individual pursuit, but it isn't. Anyone who's been in the arena knows it takes a team (or a village) to run for the highest office in the land.

With this last thought in mind, voters deserve to know who will be asked to serve in the next administration. While it's true people are keenly interested in knowing whom Trump and Clinton will pick as their running mates, they also want to know whom each would select as secretary of State, Defense or the Treasury, for example.

Donald Trump and Hillary Clinton have yet to lock up the presidential nominations of their respective parties, but you know they have some ideas about possible running mates. It's time for the pundits, reporters and voters to press them on their ideas now.
