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. Elliott Morris about Trump's and Biden's vulnerabilities within their own parties.

Later in the show the crew turns its focus to Washington to discuss the looming partial government shutdown and how immigration is continuing to grow as a key issue for voters. They also question whether a recent poll using pictures of Robert F. Kennedy Jr. is a "good or bad use of polling?”
