I understand your point now, thanks! I agree somewhat; if all you changed tomorrow in the USA was to make voting compulsory, you would immediately see redoubled efforts in purging rolls etc. I agree I probably overstated, there would still be ways to stop people voting. Although it cuts out many many avenues, so you would imagine(hope?) the overall disenfranchisement would be significantly less, and decrease over time as the attitude of voting entitlement sets in.
