The low energy spin and charge excitations in the 2D Hubbard model near halffilling are analyzed. The RPA spectra derived from inhomoheneous mean fieldtextures are analyzed. Spin excitations show a commensurate peak at halffilling, incommensurate peaks near half filling, and a broad background typicalof a dilute Fermi liquid away from half filling. Charge excitations, near halffilling, are localized near (0,0), and they occupy a small portion of theBrillouin Zone, in a way consistent with the existence of a small density ofcarriers, and a small Fermi surface. At higher hole densities, they fill theentire BZ, and can be understood in terms of a conventional Fermi liquidpicture. The results are consistent with the observed features of thehigh-T$_c$ superconductors.Comment: Latex manuscript (4 pages) + 4 postscript figures (upon request
