Barack Obama discusses the issue.
Mr. Obama yesterday also discounted Mr. Steele’s appeal among black voters.
“He may get some African-American votes, but it won’t be substantial,” Mr. Obama said. “I think the African-American community is not just going to look at someone’s skin color, but what their agenda is, and Cardin has a longer track record of working on behalf of the African-American community in Maryland, much longer than Mr. Steele does.”
