Both Obama and Romney have made lazy attempts to engage this group (that I am member of), however, I agree that neither has really focused on it. In fact, I don't think either has focused on any group much. They've both been primarily focused on the economy and how it affects everybody rather than the specific interests of every population.
That said, I don't think of the value of policy in terms of only how it will directly affect me. On the contrary, I think of every policy as something that will affect me even if indirectly. For example, since I'm done with education, education policy won't directly affect me, but it does affect the future of the country that I want to succeed. Similarly, foreign policy (likely) won't directly affect me, but it will affect the money that we have left to spend on things of value that aren't wrapped up in killing people.
In both of those examples and others, I think Obama will serve my interests more than Romney would. And I, frankly, think this notion of "I won't vote because they aren't focused on my generation" is ridiculous. Almost everything they're talking about affects your generation because it affects every generation. I can't even wrap my head around that idea.
