Looks like that whole “donate what you can” grassroots campaign strategy is working for President Obama. The president’s campaign announced Saturday it has just surpassed 4 million donors. The cash the Obama camp has raked in is impressive too—$181 million was raised in September alone. The president’s field director Jeremy Bird says the new number of individual donors sets a new record for a presidential campaign.
