Dem voters second guessing themselves about electability is a big dynamic. I actually think it's hurt Klobuchar & Booker more than Sanders & Warren. K & B are underperforming because the type of voter who worries about electability gravitate towards white men.
This is the issue. There's a swath of Dem voters who aren't asking "what do I want" but "what do Trump voters in mid-west diners" want: a by-product of certain type of New York Times coverage.
It's weird how many Dem voters have forgotten that their most successful politician electorally since FDR was a black guy named Barack Hussein Obama -- first Dem to win over 50% of the vote in a presidential election twice since 1940s.
