  We have determined the interstellar spectra of cosmic ray protons and
electrons from a few MeV to ~10 GeV. These interstellar spectra are based on
Voyager data and a normalization of specific galactic propagation model
calculations of both protons and electrons to PAMELA data at the Earth at 10
GeV, where the solar modulation is small. These resulting interstellar spectra
are then compared with spectra of protons and electrons measured at lower
energies at the Earth by PAMELA in 2009. The total amount of modulation at
lower rigidities (energies) is found to be nearly the same at the same rigidity
for both protons and electrons and ranges in magnitude from a factor ~400 at
0.1 GV for electrons, to a factor ~15 at 0.44 GV (100 MeV for protons), to a
factor ~3.3 at 1 GV for both components. The magnitude of this total modulation
of both components are the same to within + 10% from ~0.3 to ~3 GV in rigidity.
The observed total modulation for protons can be matched quite closely using a
simple spherically symmetric modulation picture involving a force field model
for the modulation and a constant energy loss at all energies. The electrons
require a set of parameters to calculate more detailed features of the
modulation using the diffusion coefficient and its variation with rigidity and
radius at rigidities less than few GV.
