Are the Democrats in danger of assuming that blacks will once again automatically vote for them.
Consider what happened to Mary Landrieu of LA who lost her longtime senate seat last election.
The deep south has always been Democratic and blacks have always voted that way.
However, blacks are starting to wake up to the fact that the Democrats have done absolutely nothing for them in return for their votes.
One could argue that they are worse off under the Obama administration.
This is an example of a powerful ad that was run against Landrieu pointing out the above.
