DAVENPORT, Iowa (AP) – After months of running on unconventional campaign strategies, Andrew Yang has arrived at a point in the 2020 campaign that is governed by the conventional rules of election. The candidate powered by online buzz is now living firmly on the real, and often uncool, campaign trail through Iowa and New Hampshire. While several other second-tier candidates are planning to use money and advertising to make an end-run around those early voting states, Yang is largely sticking to the traditional path. His campaign staff has grown tenfold since last summer, and he’s hired some well-known political hands. He’s paid for it all with strong online fundraising.
