See Candidate Page John Delaney, Climate Delaney tweets 6/26/19 Climate change is not a Democratic or Republican issue. It’s an existential threat to our planet and way of life. My plan will reduce emissions significantly in the short term and get us to net zero carbon emissions by 2050. #DemDebate #Delaney2020— John Delaney 🇺🇸 (@JohnDelaney) June 27, 2019
