The Michigan primary resulted in easy victories for both former president Donald Trump and President Joe Biden, but it also laid bare some discontent in both parties. In this installment of the 538 Politics podcast, Galen speaks with Bridge Michigan politics reporter Jonathan Oosting, POLITICO senior Washington correspondent and co-author of Playbook Rachael Bade, and 538 director of data analytics G.
