From the same Perry Bacon Jr. article on FiveThirty Eight.
You can take this to the bank.
“. . . in the 2020 election, expect Trump and his campaign, who have had a hard time casting Biden as an extremist or a radical, to make attacks on Harris with sexist and racist undertones, cast her as an ultra-liberal Californian out of touch with Middle American values and suggest that voting for Biden in November means that Harris will be running the country for 12 years.”
“The biggest unknowns are around Harris herself and her electoral skills. Harris is a good politician based on these facts alone: She was elected senator in the nation’s most populous state and in a country with a lot of race and gender discrimination, Harris is the second Black woman ever elected to the Senate, and arguably the first to be a serious presidential candidate. That said, it’s still not clear if she is a particularly strong politician on the national stage, and therefore if she will be that helpful for Democrats in the No. 2 slot in 2020 or as the main candidate in a future presidential election.”
Here’s hoping she surprises on the upside.
