I don't think they've met the burden of proof with voters. If they told people what the economic costs were going to be of climate policy and how uncertain the science actually is, there would be very little support.

My preferred course of action would be increasing animal welfare protections that put factory farms out of business. That's estimated to be a much larger contributor to climate change and it's a practice most Americans find pretty grotesque. However, it's out of sight and out of mind.

Edit: that's my preferred method after tax breaks. I'm pretty much always in favor of tax breaks.
