  We introduce a variational state for one-dimensional two-orbital Hubbard
models that intuitively explains the recent computational discovery of pairing
in these systems when hole doped. Our Ansatz is an optimized linear
superposition of Affleck-Kennedy-Lieb-Tasaki valence bond states, rendering the
combination a valence bond liquid dubbed Orbital Resonant Valence Bond. We show
that the undoped (one electron/orbital) quantum state of two sites coupled into
a global spin singlet is exactly written employing only spin-1/2 singlets
linking orbitals at nearest-neighbor sites. Generalizing to longer chains
defines our variational state visualized geometrically expressing our chain as
a two-leg ladder, with one orbital per leg. As in Anderson's resonating
valence-bond state, our undoped variational state contains preformed singlet
pairs that via doping become mobile leading to superconductivity. Doped real
materials with one-dimensional substructures, two near-degenerate orbitals, and
intermediate Hubbard U/W strengths -- W the carrier's bandwidth -- could
realize spin-singlet pairing if on-site anisotropies are small. If these
anisotropies are robust, spin-triplet pairing emerges.
