On the issue of climate change, I am sure the reason most republicans dont believe is that the issue has become so politicized and the vehemently are against the solutions the Democrats have on the issue. In my opinion, they should say yes we believe climate change is real but we oppose a Carbon Tax , or oppose new regulations cause it would negatively impact their own livelihoods.
sometimes people basically lie to pollsters just to annoy liberals.or signal disapproval..i mean obviously not everyone does that but it is a factor to consider
