If you haven't voted in recent elections, your registration may have been erased. Those Ohio Republicans are doing all they can to remove Democrats and minority voters from the voting lists.
DailyKos:
....All states cleanse their voter rolls of the deceased and people who

...a Reuters survey shows that it seems to
 be giving a boost to Republicans in the state's largest metropolitan 
areas. In Ohio’s three largest counties that include the cities of 
Cleveland, Cincinnati, and Columbus, roughly twice as many voters have 
been removed from the rolls in Democratic-leaning neighborhoods as in 
Republican neighborhoods. Just another effort to shave a percentage 
point or two off Democratic turnout...
The Ohio Republicans are cheating again.
