Democrats don’t fear them voting Republican...they just fear they won’t vote.
In many races around the country, Blacks not turning out will be a loss of 20 House seats for Dems.
That adds up in election after election.
You're right. The Dems also fear the end of tampered inner-city voting precincts with the usual dead people, dogs, and mega-voting. It's rare that 120% of their electorate happen always to vote for the Dem in any given race, but they manage to pull it off ;-)
