Didn't they also "promise" to release the Epstein files?
Good luck with that.
Good luck with that.
You didn't get a vote. You got a "promise" of a vote. From a party who is disappearing nannies & gardeners and zip-tying children. A party who has flushed Due Process in America down the toilet. Who has subjugated its Congressional duties to an autocrat. That's what everybody sees, Tim.
Kaine on why he thinks just getting a vote on healthcare is a win: "We're the minority party, but everybody will get to see who is standing for them when it comes to lowering their healthcare costs"

Hey #Math teachers,
Start telling (or reminding) your students that:
Subtraction 𝙞𝙨 addition (...by the additive inverse); and

In other words, subtraction & division are 𝘿𝙀𝙁𝙄𝙉𝙀𝘿 as:
a - b ≝ a + (-b)
a ÷ b ≝ a × b⁻¹

"Electoral reform would be tantamount to enacting political antitrust legislation."
Exactly. Politicians shouldn't be allowed to set the rules by which politicians are elected. This is the job of an independent, non-partisan body in the form of a Citizens' Assembly.

If Democrats think that the *long-term answer* to dealing with Trump's disastrous presidency is to simply vote him and other Republicans out, they are mistaken.
The *structural weaknesses* that have been exposed by Trump need to be addressed.
Will they actually do this? Almost certainly not.

Trump threatened to cut funding if New Yorkers voted for Mamdani. They did it anyway | CBC News
Zohran Mamdani wasted little time after becoming mayor-elect of New York City before addressing the man who threatened to not only defund the city, but also to arrest and deport him if he won.

Got our flu and Covid shots today! I love independent pharmacies for the ease with which you can get your vaccines. Phone them and a real person answers. Walk-ins are welcome. No frustrating online booking system. Easy peasy lemon squeezy.

Your regular reminder that we desperately need to overturn Citizens United and get big money out of politics.
It is among the worst Supreme Court decisions in history.
It corrupts our political system every day.
