Hi NE Queens and Long Island!
It's a gorgeous day here in Fort Totten, and @aengelnyc.bsky.social and I are here collecting signatures to get in the ballot (we won't sell your data)!
We can't have better leaders without primaries.

I just want to make sure that everyone knows Trump's war of choice in Iran is costing us $900 million a day according to the latest figures
Not $900 a day, not $9,000 a day, not $90,000 a day, not $900,000 a day, not $9 million a day, not $90 million a day
$900 million a day
Image of a New York Times web version story preview. Headline: Trump Wants to βTake Overβ Elections. These States are Prime Targets. Subheadline: President Trump thinks Republicans should control voting procedures in parts of the United States. But where? Here are some possibilities.
No mention in the headline/subhead that Trumpβs takeover plot is wildly unconstitutional.
The story is better & discusses GOP election subversion but still doesnβt note a fed takeover is unconstitutional (or that NCβs GOP takeover attempts were ruled illegal until they flipped the NC Supreme Court)
Very cute!

Comprehensive presentation of the "Theorem of the Day", starting with a statement of this theorem. Singmasterβs Binomial Multiplicity Bound : For integer k > 1, let N(k) denote the multiplicity of k as a binomial coefficient; i.e. N(k) =β£{(n, r) β Z^2 : k = "n choose r"}β£. Then N(k) = O(log k).
