My new column for Bloomberg Opinion is about infighting among Democrats.
McCaskill managed to hold a Senate seat for 12 years for the Democrats in a state that has been turning more and more Republican. Her audacious intervention in the Republican primary in 2012 helped her hold a seat she had been expected to lose. Ocasio-Cortez, meanwhile, represents a district where 77% of the voters went for Hillary Clinton in 2016. If you had to pick one of them for advice on how to expand the Democrats’ appeal in parts of the country where it’s struggling, of course it ought to be McCaskill. . . .
