She must have looked good enough to eat.

A jovial Joe Biden nipped his wife Jill’s finger onstage Saturday at a rally in Council Bluffs, Iowa, as she introduced him at the first stop of an eight-day, 800-mile road trip through the first-to-caucus state.

As Jill Biden flung an arm wide to make a point, her husband theatrically dodged her hand — then, on a second pass, gave her a playful chomp on her fingertip.

She took the nibble in stride, laughing along with a crowd of about 200 supporters.

Biden’s “No Malarkey” tour, the most intense campaign swing of his 2020 presidential bid, is meant to boost his flagging support in Iowa, where polls show him trailing Vermont Sen. Bernie Sanders, Massachusetts Sen. Elizabeth Warren and South Bend, Indiana, Mayor Pete Buttigieg.
