Warren as Biden's running mate makes no electoral sense

Biden’s actually doing quite well on his left, for example. An average of recent live interview polls shows that Biden’s getting 85% among self-described liberal voters. Trump’s scoring just 9%. Four years ago, an average of pre-election polls taken after the third presidential debate put Hillary Clinton at 77% and Trump at 10% among self-described liberal registered voters.

In other words, Biden is doing better than Clinton did among self-described liberals.

Another group where Warren showed real strength in the primary season was among white college educated women. In states with entrance or exit polls, Warren got 22% of their vote on average, compared to the 13% that she got overall in those states.

Like with liberals, Biden is performing very well for a Democrat among white college educated women. An average of recent polls puts Biden at 61% and Trump at 36% among them. The final pre-election polls from four years ago had Clinton with a 52% to 36% edge.
