No campaign has ever touched on all the important issues, but who decides what's worth discussing and when? For the first time since the election of 1988, the issue of climate change – a subject even the Pentagon says could be crucial to America's future -- was not raised in any of this year's presidential or vice presidential debates Both presidential candidates are being accused of "climate silence."

Are the candidates trapped by partisan polarization? We hear a range of opinions.
