There are a lot of facets involved in this question. Let me start from my point of entry. I believe, based on the environmental, economic and civil liberties policies of President Obama that it is against the interests of America to vote for either him or any likely GOP candidate in 2012. The time is short for the world's climate, according to leading authorities.

Obama sold us out at Copenhagen in 2009 and has proved to be deceptive about his campaign promises in that regard.

Still, the issue is complex and that is why I am inviting a reasoned debate on whether an attempt should be made to get Bernie Sanders (or someone else) on the ballot in 2012. Someone who will advocate for policies which lead to environmental and economic justice and the survival of the people of the world.
