Environmentalist — becoming a dirty word, by Joanne Nova.

Once upon a time, nearly everyone was “environmental.” After the first glorious Earth Day fully 78% used the term to describe themselves. Incredibly in 1991 just as many Republicans identified as environmentalists as Democrats did.  Now only 42% of all Americans would use the term.

The long term trend appears inescapable. The Republicans are about 20 years ahead.
