BUSH: Look, I admire the fact that Governor Kasich is supporting spending more money on drug treatment and mental health. I think that’s a high priority all across this country, but expanding Obamacare is what we’re talking about, and Obamacare’s expansion, even though the federal government is paying for the great majority of it, is creating further debt on the backs of our children and grandchildren
Diving into this you see that there may have been some red herring with Governor Kasich trying to divert the question of Obamacare. With Bush's response to this question you see that the audience is mostly likely the younger generation. I think this because he feels compelled to acknowledge children and grandchildren. In turn you find that this is extremely appealing to the audience. When talking about the younger generations as a candidate you hit the bell, most everyone cares about how the choices we make today affect the future and by acknowledging this you create a great amount of credibility for yourself .
