  In view of the precise data available on inclusive polarized electron
scattering off polarized proton targets in the nucleon resonance excitation
region, we compare these results with the coherent sum of resonant
contributions to the polarized structure function $g_1$ and virtual photon
asymmetry $A_1$. To this goal, we employ the nucleon resonance
electroexcitation amplitudes determined for photon virtualities $Q^2$ $<$ 5.0
GeV$^2$ from analyses of the CLAS data on exclusive electroproduction off
protons in the resonance region. Most of the well established resonances of
four star PDG status in the mass range up to 1.75~GeV are included. We find
that the resonance-like structures observed in the inclusive $g_1$ data are
related to the resonant contributions in the entire range of photon virtuality
$Q^2$ where the data on $g_1$ are available. In the range of invariant mass of
the final hadron system $W$ $>$ 1.5 GeV, the data on the asymmetry $A_1$ are
well reproduced even when accounting for resonant contributions only,
especially for the larger values of $Q^2$ and energies analysed. This
observation offers an interesting hint to quark-hadron duality seen in
polarized inclusive electron scattering observables.
