I doubt there are enough climate voters to matter.
On a personal note the political group Im with had over a thousand volunteers for Biden in 2020,around 20% were single issue climate voters.Nearly all of them voted for Bernie in the primary and reluctantly voted and volunteered for Biden because he promised no more drilling.Needless to say they wont be voting or volunteering for Biden in 2024.Biden supporters cant even tell them the republican will be worse when Biden issued more drilling permits than Trump his first 2 years and this year The US has the highest oil production in history of any nation.
