Apparently a memo was leaked yesterday from a South Carolina focus group, where it was found that black voters are "uncomfortable" with Pete Buttigieg being gay, and won't vote for him.
While liberal on most other issues, many black voters have not warmed up to the mainstream acceptance of gays, and they quietly will display that at the ballot box. When Proposition 8 passed, which made same sex marriage (briefly) illegal in California, it was discovered that the "Yes" side managed to defy polls because black people showed up to vote for Barack Obama, while simultaneously voting yes on 8. Often these same voters kept these anti-gay sentiments to themselves when asked during opinion polls, thus leading to the surprise victory of prop 8.
Anyway, it's hard to win the Democratic nomination if barely any black people support you. This not only plagues Buttigieg, but also Warren and Sanders.
Hence another reason why my +500 bets on Biden are a steal.
