Your comment about Repub leaders deserves some thought. If we view them as a group seeking to win political support, then they probably use the typical consulting approach of analyzing data, trends, and thinking of messages that will appeal to each “group” but not alienate them.
That approach might work for rational, business investment planning but when trying to persuade individuals to behave in a supportive manner (vote and send money) you must understand the psychology of individual decision making.
Yes, I agree Blacks and Hispanics are potential supporters. But, you have to understand the psychology. It is interesting to note that Romney got young Blacks’ support without direct appeal. That hints at young Black’s economic desires and still looking forward to a future of economic opportunity. If you get some rich Black celebrities to brand your message, you can get the hopeful young Black’s hopes up. If you point to your opponent as having a silver spoon-in-mouth upbringing by a white banker, raised in Hawaii and Indonesia, and having a white parent from Kansas—then ask the Black group just how much they have in common with him, then you start to challenge the identification. If you tell the Hispanics that you will move them from just working to owning the workplace and you tell them you draw the contrast between life in the places they or their ancestors came from and what you will protect for them here—you might start to make the connection. There are male-female differences that must be tackled in a different way—there are different psychologies. It is done on a one-on-one level. It takes contact. You must counter other messages they receive with ridicule.
Just some thoughts—not meant to criticize anyone.
No offense here - I totally agree.
