Not necessarily says Gene Healy:"Yet, here’s an interesting fact: Recent Census Bureau figures predict that the working-age population will be 55 percent minority by midcentury. It may be hard to imagine the Tea Party movement becoming a Rainbow Coalition. But it’s even harder to believe that minority voters will enjoy paying for the (mostly white) baby boomers’ retirement and health care while they’re working to support their own families."
That's an interesting thought but I think the GOP will need to be crushed harder before it decides it needs to market itself towards a more diverse array of voters. Given that this midterm election is going to be a positive one for the GOP it is unlikely that such a change will occur anytime soon.
