How To Cure GOP Demographic Blues

If you read this maybe you could explain to me why it is that the GOP has  Them Old Time Demographic Blues.

“I see that the way we will get the Hispanics and the other groups, the Asians, as part of the Republican Coalition is to get them first part of the great American Coalition. Make them think of themselves, not make but, persuade them to think of themselves primarily as Americans. Restore the overarching, all-encompassing concept of an American identity, which we used to have, which we knew how to bring about and which in the last 20 or 30 years very largely as a result of the democrats wanting to emphasize ethnicity rather than American-ness. We have lost that and frankly one of the reasons we have not regained it and doing very badly at the moment is because the Republicans have neither had the imagination nor the courage to think how they could appeal to these other ethnic groups as Americans and craft an appeal that won them over. They have got to do that.”

I think they may be onto something (or maybe on something).  You really don't expect me to comment on this... do you?
