Overnight, AIPAC leapt to the top echelons of big money funders of US elections - but as Velshi points out in his presentation, the others are all oriented around domestic US politics. AIPAC is the sole PAC of that list whose focus is entirely on America's relationship to a foreign government (Netanyahu's RW fascist coalition).
GOP-AIPAC funding is a new, huge threat to the integrity of Democratic elections.
Going from roughly $20m to $100 m in expenditures is a flood of anti-Dem interference.
