I'd say 3 as Griffin Bell will do it tomorrow and he has been very influential especially in legal circles. Plus the GA dem said they would not only travel GA but possibly the South in general to campaign for Bush as many are moderates and that could help esp in FL and in senate races.
I'm watching Ed Koch (former democratic mayor of New York city) on Capital Report detail all the reasons why he's going to vote for Bush in 2004.
He's called Dean "McGovern 2" and said that the democrats running for president in general "don't have the stomach" to adequately fight terrorism.
That makes two major democrats who've endorsed Bush.
