"Look! Up in the air..."
True about the Green Party, which is why the name is not viable. Considering the attitudes of the greater populace, the party name must avoid any international connection. Also to be avoided are words such as Workers and People, as those bring to mind Communist groups. And you have to stay away from Progressive and Liberal, as the current mood abhors anything described as liberal (while, at the same time, liberal policies themselves are widely admired). And, naturally, you have to avoid any flag-waving terms like Freedom and Liberty, as that whole genre of terms has been claimed by the far right.
