The Green Party has an agenda that reaches well beyond simply advocating for the environment. Here are some examples of laws that they say (go to their website to see more) they would like to enact.
- They want the government to create a single-payer health care system for everyone. In other words, they would have the government provide everyone's health care.
- They would like to decriminalize marijuana.
- They want to have the President and Vice President elected by popular vote.
- They would like to end the war in Afghanistan and the US troop presence in Iraq.
From this, you can see that the Green Party is a very liberal party that takes positions that are well to the left of what most Democrats are willing to call for.
