If Lieberman does speak at the Convention then the Dems can count on at least splitting the Jewish vote. I know Joe is a McCain supporter but being given the honor of speaking at the Convention after what the Democratic party did to him in 2006, that could sway some of the not so hard core who might be worried about Israel crowd!
My memory floats back to Zell Miller speaking at a Republican convention. THAT was a speech I don’t think anyone can top.
