Well, it's quite a horse race.
Hard as it is to keep track of who's on first in the presidential primaries, it's even harder to stay up to date with where each candidate ranks environmental and planetary climate issues.
It seems that most of them, democrats and republicans alike, have waited as long as possible to make any statement at all about their views and commitment to mitigating global climate change and environmental degradation.
What can those of us serious about more sustainable lifestyles and public policies do?
Well, when pollsters call you, refuse to answer unless they will listen to you ask for information about the candidate's position on climate change and resource protection.
Call candidates offices, and ask whoever is taking calls to have one of the policy people call you back (they may not return your call, but if a lot of us ask, they will start to feel nervous about their neglect of the issue).
Send emails to candidates campaign websites, demanding their platform on the environment.
Tell those you won't support because of their position (or lack of one) why.

This time around may be our best shot - and maybe our last chance - to make our political scene responsive to urgent planetary environmental issues that will shape life - and politics - for many human generations.
