Why don't environmentalists vote?

Why is it that a majority of Americans believe climate change is real, human-caused and are worried about it, yet consistently rank "environment" near the bottom of their list of concerns in elections?  The folks at The Environmental Voter Project (EVP) have some answers and well-conceived ways of bringing their insights to specific local, state and national political races to tip the balance.  As they quipped recently, there's a sleeping lion in the bushes waiting to be waked and EVP's rustling!  [hint: next Thursday's special election in Georgia to fill Tom Price's seat in Congress]
