RFK Jr. just cancelled a bunch of grants that are fundamentally aligned with MAHA priorities, including fresh produce delivery and home visits to assist women who’ve just brought home a new baby. Why? Because these grants focused on underserved populations. Can’t have that, can we?

Previously: As of August 3, more than 474 gigawatts worth of large-scale projects are waiting to connect to the Texas grid, more than 5 times the grid's previous peak demand. Roughly 90% are AI data centers.

Who Pays for the High-Powered Grid that Data Centers Need?
Texas would make large AI hyperscalers pay for the wires that connect them. Whether they must also pay directly for the broader grid work needed to serve them is still an open question.

There’s been a lot of talk in this race about what makes a "real man." A man does what’s right when no one is watching. He upholds his commitments to his family and neighbors. He doesn’t lie, cheat, & steal his way through life. Real men serve others. Weak men serve themselves.

From our magazine: GOP legislators repeatedly insisted that “Texas Education Freedom Accounts” would be open to any and all types of private schools—of all creeds and persuasions. In predictable fashion, they haven't quite lived up to that promise.

School Vouchers Are What We Thought They Were
The nascent "freedom accounts" program is, predictably, burdened by Republicans’ insistence on religious discrimination—and likely set to benefit those already outside the public school system.
