The Steyer Brothers: “We’re Fearless”  → Politico’s Stephanie Simon and Caitlin Emma profile Tom and Jim Steyer, two wealthy brothers aiming to be major political players and inviting comparisons to the Koch brothers. Billionaire Tom Steyer already made headlines when he poured money into the Virginia governor’s race to help Democrat Terry McAuliffe eke out a victory. He’s now promising to spend at least $100 million this fall backing candidates who will combat global warming. Now his older brother Jim –  a children’s advocate  focused on education, technology, poverty and privacy –  is promising to raise  millions of dollars to stock his war chest in order to enter the political fray. As he told Politico, “you don’t bring a squirt gun to a fight where the other guys have AK-47s.”
