"WASHINGTON — Ardent climate change voters thought Campaign 2020 was going to be their election.
Gov. Jay Inslee of Washington centered his entire presidential campaign on the issue. When he dropped out, Tom Steyer, Senator Elizabeth Warren and Senator Bernie Sanders each clamored for the mantle of ‘climate candidate’ with a series of increasingly ambitious calls for action.
Now, some climate-focused voters said they are struggling with their feelings as former Vice President Joseph R. Biden Jr. appears certain to become the Democratic nominee. In interviews with two dozen activists and voters who consider the planet’s warming their top issue, almost all said they worried that Mr. Biden has not made the issue a sufficient priority or been specific enough about his plans.
“The response to Biden on climate change ranges from suspicion to resignation,” said Megan Mullin, an associate professor of environmental politics at Duke University’s Nicholas School of the Environment."
