Democratic Presidential Hopefuls Spend Heavily on Digital Ads, Staff Reuters WASHINGTON/NEW YORK - The crowded field of Democratic presidential hopefuls has spent heavily on digital advertising, investing early in ads that may bring more name recognition and help raise money, according to disclosures filed late Monday. The timing of spending decisions for a presidential campaign could be critical. Candidates that spend too much too soon could find themselves without enough cash to pay staff or purchase advertisements as voters head to the polls. However, a candidate who doesn't spend enough early on could also miss the opportunity to build name recognition and bolster support. Former Vice President Joe Biden invested the most heavily in digital advertising, spending $3.5 million on online ads in his first two months in the race, according to disclosures his campaign filed on Monday. U.S. Senator Bernie Sanders was a close second, spending $3.4 million this year. .
