It makes zero sense to vote Trump for president and then Kander for Senator, but it's Missourah... If only they could run Rob Portman in Missouri, lol.
It actually makes a fair amount of sense IMO. Trump is juicing white ConservaDem turnout to the max, and most of these voters are used to voting for downballot Dems, particularly those who appear at least somewhat moderate.
We'll probably see this most in rural southeaster Missouri in the Lead Belt and the Bootheel and in "Little Dixie" in Northeastern Missouri.
