"...voting for Nader, however, will just put to rest any chance of changing things"

Larry, you keep stating this as if it were a hard fact. It isn't fact, it is your opinion. Your opinion, like many others who share this particular opinion, is informed by your anger and frustration at George W. Bush getting into the White House in 2000. The facts don't support the conclusion that Bush getting the White House is Ralph Nader's fault, but it doesn't stop you from repeating it.

I believe it would be much more productive for dissaffected Democrats such as yourself to actually do something in support of the person you feel to be the best candidate for the job this year, instead of remaining fixed upon and obsessed with keeping the greatest myth of the 2000 election alive.

There is plenty of guilt and blame for environmental degradation to go around, and it doesn't simply lie on the doorstep of the Republican administrations. It also lies with the Clinton administration, the Carter administration, and with the Democratic Party establishment.

There is but one major cause of environmental degradation, and that is greed. Greed isn't influenced by one particular partisan ideology or the other. It is only concerned with how to best take advantage of the direction the political winds are blowing.
