Sanders campaign down to less than $6 million in cash

WASHINGTON (AP) — Bernie Sanders' campaign had less than $6 million at the start of May, a critical cash shortage as he makes an admittedly tough final play to wrest the Democratic presidential nomination from Hillary Clinton.

Since he started his presidential bid, Sanders has spent nearly $207 million, about $25 million more than Clinton's $182 million in expenditures.

Even as he racked up primary victories last month and sharpened his attacks against the former secretary of state, online donors started holding back.

The campaign paid $17.3 million to Old Towne Media Inc., based in Alexandria, Virginia, and more than $3.6 million to Revolution Messaging, a Washington advertising firm that concentrates on digital outreach.

[...] the DNC and state parties that have benefited from Clinton's fundraising help have begun investing in likely general election battleground states such as Ohio and Florida.
