But why be partisan? Why not vote independently, after an earnest scrutiny of the candidates and issues, for the welfare of the people as a whole? It sounds good and it would be very nice if it would work. It would also be nice if pi were exactly 3.000 instead of a bothersome 3.14159 plus.

There are two reasons, one moral and one practical. The practical reason is this: You simply cannot be effective in politics unless you join in the process of compromise and conciliation whereby free men merge little groups into big groups until they accomplish a government. If you are not partisan you are on your own, everybody is out of step but Johnny, and the chances that you can have any effect on how this country is run are 140,000,000 to one against you.
