The independent expenditure effort was heavily supported
by charter school supporters like Paul Singer, a
wealthy hedge -
fund manager and investor who supports charter school expansion, as well Daniel Loeb, a director at Success Academy and Dan Senor, a former Bush administration official who is married to former CNN anchor Campbell Brown, a critic of teacher tenure.
The mobilizing began in late June and early July, when
wealthy donors like
hedge fund managers Paul Tudor Jones and Daniel Loeb, Wal - Mart heirs Jim and Alice Walton, and financier Roger Hertog donated heavily to committees backed
by education reform groups.
