Sen. Bernie Sanders (D-VT)
Sen. Cory Booker (D-NJ)
Closest states are CA, CT, IL, MO, MA, NM, NV, and HI. Booker significantly under-performs Clinton among more conservative Southern whites (but still has sizable margins in the South) and among Midwestern white females (allowing Sanders to expand on his 2016 margins in MI/WI/MN and to narrowly win OH/PA/IL). The only state where Sanders does significantly worse than he did in 2016 is Hawaii, which he still wins.
I think Booker will do much better in Colorado and much worse in TN and Arkansas than Clinton. Also, better in Massachusetts, Oregon, Washington. BTW, why would Booker do well in New Mexico?
