From a flyer or something published for the 1848 presidential campaign, images of the Whig Party ticket, Zachary Taylor for president and Millard Fillmore for vice president:
"Zachary Taylor, People's candidate for president; Millard Fillmore, Whig candidate for vice president"
We probably shouldn’t read anything into Taylor’s being identified as the “People’s Candidate” and Fillmore’s being identified as the “Whig Candidate.” Probably just the copy writer’s way of not sounding redundant.
Found it at the massive digital image collection of the New York Public Library. Image details from the NYPL:
