Well, a lot of that half live in places that have been massively impacted by drought, flooding, hurricanes, tornadoes, and other things that are made much worse by climate change.

This year is the first year I’ve personally been impacted by wildfires (4000+ hectare fire on the edge of my town), and it made climate change 10x more real for me than it was before, and I was fully on board before! How long can the right stay on the wrong side of history with respect to climate change when they are losing their homes and farms and dealing with one thing after another?

To butcher a perfectly good quote: It is hard to get a man to understand something when his personality and all of his social connections depend on his not understanding it.

In other words, I wouldn't hold my breath.

Conservatives make up ~30% of the population. The so called "independents" fall for Conservative propaganda because that's all of our media and here we are.
