This is probably very bad news for the democrats in Maryland. Much of the black Democratic local leadership of Prince George's County has endorsed Steele. They say their concerns have been repeatedly marginalized by the Democratic Party and that Steele is a good man. Prince George's County is a huge county with a huge black, Democratic base and this is, unfortunately, likely to reverberate. It could throw the election to Steele and the Senate majority to the Republicans. This is a short diary, but it doesn't look as though anyone has posted it. You can find details in the Washington Post online. Sorry to bring such bad news. Things have been looking so hopeful.
Update: This is in the Washington Post - it is a fact. I'm so sorry you don't like the news - neither do I. I rarely diary and I won't do it again. Should not shoot the messenger. No question at all that this will affect Steele's numbers. The only question is whether it will be enough to put him over the top.
