After months and months of speculation, former Vice President Joe Biden announced he’d be running for president in 2020. Already an early frontrunner, Biden joins a crowded field of potential Democratic nominees. There are now more than 20 candidates running, from policy wonk Elizabeth Warren to newcomer Pete Buttigieg to 2016 veteran Bernie Sanders. The Iowa caucuses are nine months away and if everyone stays in the race, it could challenging for voters to keep track of where the candidates stand on critical policy issues like healthcare, taxes, and climate change. This week on Money Talking, WNYC's Charlie Herman talks to Rick Newman, senior columnist for Yahoo Finance, about some of the fiscal policies being put forth by the Democratic contenders — and what they might mean for your pocketbook.
