On Thursday, the Sanders campaign announced it raised $15m since 30 April from 250,000 donors, many of whom have made small contributions online. In contrast, Barack Obama attracted only 180,000 donors during the first quarter of his presidential campaign in 2007, which has been considered the benchmark for online fundraising by an insurgent candidate in modern presidential politics.The senator, propelled by a groundswell of support, is also gaining ground on Clinton in polls emerging from across the early voting states.
