Elected officials who ride in Air Force Two: Abbr.

VPS

They serve as president of the Senate and are first in the presidential line of succession after the commander in chief. Think of the role often paired with the phrase "a heartbeat away."

This clue asks for the abbreviation of the elected officials who travel on Air Force Two, which is the call sign for the plane carrying the U.S. vice president. "VPS" stands for "vice presidents," plural, since the clue hints at multiple officials (though typically only one serves at a time). The "Abbr." tag signals that the answer is shortened, and the mention of Air Force Two is a direct nod to the VP’s role.
