Safe?? A woman who’s black is not a safe choice in America. Sure, the progressives and BLM folks will like it and there won’t be criticism from those quarters, but it’s not like you can lose those voters to Trump.
The VP choice is going to be fine in most states. In some, the Dems will lose even worse because of it.
I doubt that anybody who was planning to vote for Biden would change their mind because he picked Harris.
Anybody who won't vote for a black VP or a woman VP or a black woman VP was probably never going to vote Democrat anyway.
Anybody who won't vote for a VP known as a tough prosecutor probably already lost interest in voting Democrat when Biden won the nomination.
Harris is a choice that won't alienate anybody who was going to vote Democrat, and she is a choice that will energize some who might have been unexcited about voting for Biden.
