I don't have much else to add, since others have already pointed out repeatedly that Democrats have been actively courting minority voters — African-Americans included — for decades. That the current President is black doesn't make this some sinister plot for a racial minority to go all chestburster on the nation.

Whites in the US aren't struggling with racial discrimination nor do we have special issues that effect us relative to the average American (since, as far as race goes, we are the average), so a "European-Americans for ____" group would be impossible and pointless. Romney would be crucified because the only people a "White Americans for Romney" or a "European-Americans for Romney" group would appeal to are the white supremacists, as the rest of us would scratch our heads and said "Why do I need a racial advocacy group? The Man isn't keeping me down for being white."
