According to the Wayback Machine, the Reagan Library's video of his address "on free and fair trade" had just 274 views last December.
It had 232k views at the time of the last snapshot, in July.
Today it's about to cross half a million.
Meant to post this sooner. Inflation hit 3% Y/Y. Not as hot as could have been but still warm. Troubling that 40% of the data are now imputed due to staffing shortages prior to shutdown.

Supreme Court ruling: "This Court now concludes that independent expenditures, including those made by corporations, do not give rise to corruption or the appearance of corruption. That speakers may have influence over or access to elected officials does not mean that those officials are corrupt. And the appearance of influence or access will not cause the electorate to lose faith in this democracy."
Every now and then I go back and read the Citizens United ruling to see if it is as unhinged as I thought, and every time I do that I see it is actually far more deranged than I remembered.

The Virginia Senate just told UVA it’s not getting state funding if it accepts the compact since UVA exists to serve Virginia, its residents, & their interests—not be a tool of the federal govt.

This is described as an "exemption" but since the UK and EU plan to align carbon markets so that UK and EU firms will pay the same price that's not quite right. It's instead aligned w the EU intent to credit domestic prices already paid. More a mini coalition!

“It starts with a safe virus that has been altered to contain a specially designed sequence of DNA.
This is infused deep into the brain…
The virus then acts like a microscopic postman – delivering the new piece of DNA inside brain cells…”
Today we got a (very reasonable & completely warranted) explanation from the Bureau of Labor Statistics for why they are delaying publication of the annual Consumer Expenditure Survey (CEX) by about a month.
Transparency is good!
