This is exactly it. All Trump and the GOP have done is KILL clean energy projects left and right to cut deals for their polluter buddies.
To actually have real negotiations on permitting reform, they must first stop their war on clean energy.

For me it's the way the press pool just quietly went along with it because he's the president
The entire point of this country is that we don't have to let some guy do whatever he wants just because of his title. We don't have to respect him or go along with him just because he holds an office

I don't know why the "Piggy" thing is bothering me so much. It's one more unforgivable thing in a list of 20,000 unforgivable things, but I've been mad about it for like 12 straight hours.

Democracy kinda depends on voters hearing accurate facts and analysis more than they hear made up nonsense, and that’s kinda sort of an issue
The actual finding here is that a huge percentage of the population believes things that are not true. Democrats objectively did not spend significant time on climate change or LGBTQ issues in the last election campaign.
Duh. Those of us on the ground last year actually speaking with middle class/working class voters and who heard from these voters every single day the same - “Trump is an asshole, but Democrats are out of touch” - could’ve saved my new political party a lot of time & money producing this “report.”👇
