I think it's correct as-is. Inserting a "were" would make that clause read as independent. With how the sentence is currently structured, that doesn't work.
That's not to say you couldn't have
The tracks are now unruley [sic] and wild—the people once tied to them were killed in crosswalks by giant trucks
if you want, but the comma needs to change to something like a dash or a semicolon. With a comma (i.e., as a subordinate clause), "were" doesn't make sense.
Because he defederated them?
The object doesn't absorb their mass, but rather their energy (which admittedly can be equated to a mass via a factor of c^2, but that's not actually what's happening). The change in momentum that results from a photon hitting you isn't caused by a change in m, it comes from a change in v. If mass were the quantity being transferred, solar sails wouldn't work to move anything; they would just sit there and get more massive as photons hit them.
Here is my attempt at digitizing that plot and then log-scaling the vertical axis.

Yes, because now you've added the critical qualifier "who have ever been on the ballot". Without that, it doesn't hold.
No black woman has ever won the election or lost the election, because the set of black women who have ever been on the ballot before is empty.
Not really, since in most (all?) U.S. presidential elections to date there has not been a black woman on the ballot. I think there's an important semantic difference between losing and not winning. The equal but opposite statement to the OP would be that a black woman has never won the election, which is true.
Huh? It's referenced by name right there in the screenshot...
