You should account for GDP. Electors have zero bearing on military capability. If you're going to give Wyoming three armies, then you need to give San Francisco three, Oakland three and San Jose three as well.
If you want to do it right, a lot of states should start with one army of just be neutral.
Looking at a more realistic scenario would be
California: 14 units
New York: 8
Texas: 9
Florida: 5
Illinois, Pennsylvania: 4
Ohio, New Jersey, Georgia, North Carolina, Massachusetts, Virginia, Michigan, Washington:3
Maryland, Indiana, Minnesota, Tennessee, Colorado, Wisconsin, Arizona, Missouri:2
Everyone else: 1 or 0
