DETROIT If the Democratic electoral earthquake of 2018 had an epicenter, it might have been Michigan.

Two years after the party shockingly lost the state to President Donald Trump , Democrats romped. Their gubernatorial candidate, Gretchen Whitmer, won by an impressive 10 percentage points. They swept races for U.S. Senate and attorney general, passed progressive policies via referendum including marijuana legalization, automatic voter registration and creation of a commission to end gerrymandering and flipped two GOP-held seats among the states 14-member House delegation.

So it seems like it will be a good idea for whoever emerges as the 2020 Democratic presidential pick to listen to 2018s victors. One problem: key Michigan Democrats cant agree on what exactly the playbook was.
