When it comes to the likelihood of car crashes, or the deadly consequences of car crashes, speed is ALWAYS a factor. #UrbanTruth
Graphic with a faded image of mangled vehicles after a car collision. The main text is a quote that says “speed wasn’t a factor.“ The tagline at the bottom says speed is always a factor. The ad is from the Urban Truth Collective.

It's very difficult for countries to simultaneously transition away from coal and increase electricity per capita consumption Arguably only a few countries have pulled it off at the same time:

A Virginia guy hunted a Latino man, cornered him, questioned him, and then shot him and his friend, because he assumed the guy was an undocumented immigrant. He was radicalized by Fox News etc. and, of course, Trump. www.wric.com/news/local-n...
“[Cornett] then described his anger at illegal immigration, telling the detective that he was ‘pissed’ about undocumented migrants receiving welfare funds, phones and health insurance, and that he had ‘driven around before with the same thought,'” court documents state. “[He] later asked the detective whether he could be ‘charged for [his] thoughts,’ and went on to explain that he fantasized about flying an Apache helicopter gunship to the border and firing on undocumented migrants traveling into the United States in order ‘to deter’ other undocumented migrants from attempting to cross the border.”

Cornett’s housemates also told detectives that he was “kind of obsessed” with cable news stories about undocumented immigrants entering the United States.

Notably, neither victim was identified as an undocumented immigrant within court documents.

I don't know why this paper is open in my tabs, or who sent it to me, but it's important! It's about the Democrats' faith that good policy will yield political support, which appears, with some examination, to be wrong.

Trump’s National Energy Dominance Council should appoint a ‘hydropower czar’
Federal hydropower can help meet load growth, onshore manufacturing of key defense components and help address burdensome regulations.
