After an Ohio teacher put up a poster in their classroom reading "hate has no home here," the school board said it violated a state law against instructional materials related to sexual orientation or gender identity. Anti-LGBTQ censorship laws do nothing to help kids learn and grow.

Anti-hate poster has no home in Ohio classroom, says school district
The poster, which included a rainbow flag, counts as 'instruction that includes sexuality content' according to the board.

NEW: Virginia just passed a law to join the National Popular Vote Interstate Compact, giving it 222 of 270 electoral votes needed to activate. This map and spreadsheet show which states could join to activate it by 2028 depending on the outcome of the 2026 elections docs.google.com/spreadsheets...
Electoral College cartogram showing which states are in the National Popular Vote Interstate Compact and which ones could join in time for it to activate by 2028. Each state is sized and labeled according to its number of electoral votes. The states are spaced out enough to accommodate the changes in size but retain their general shapes and relative positions on the map.

Current members are in solid orange, potential members are in light green, and nonmembers that are unlikely to join are in medium gray. Members have 222 electoral votes, potential states have 68, and the unlikely states have 248. The compact would only activate once states with at least 270 electoral votes have joined.

The seven potential members and their electoral vote are Alaska (3), Arizona (11), Michigan (15), Nevada (6), New Hampshire (4), Pennsylvania (19), and Wisconsin (10). Democrats would need to gain the governor's office and/or legislative chambers to win unified power in these states, as detailed in the spreadsheet linked in this post.

Orbán's electoral crushing is a far greater achievement than most people outside Hungary realise. He systemically consolidated power for 16 years, fixed the electoral map, abused govt power for political purposes & censored media. The hurdles that Hungarians overcame for this moment were immense.

Here are some of my favorite signs from the #NoKings protest in Willimantic CT. I know some people are gonna say sign holders aren't doing enough, but as someone who has also written emails, signed petitions, called Congress reps, boycotted, donated $, & more, stop yucking our joy.
Long sign says "Waiting for the fall". A stack of blue turtles, stand on top of each other with the king in red on top, sweat falling off many of the turtles under the angry orange faced wing with the blond wig. It looks similar to a book by Dr. Suess. Each turtle has a different wordon it's shell: the law, justice, education, environment, federal workers, LGBTQ, Latinos, BlacksPerson wearing a coat holds sign that says "We hold the Bachelorette to Higher Standards than the President"Make America Matriarchal Already !!!Prevent Truth Decay. Two teeth, one with a hole, on a red background with a large toothbrush made of scrubbers. And the sign handle is the toothbrush handle.
