CHARLOTTE, N.C. — Though his support has surged in early caucus and primary states Iowa and New Hampshire, 2020 Democratic hopeful Pete Buttigieg has low polling numbers in states with a more diverse voting base. In South Carolina, he is polling in the very low single digits, which is a step up from his former number of 0%. Though he has funds and momentum, the South Bend, Indiana, mayor might hit a wall in a party that depends on a strong African-American and Hispanic voting base.

Minority voters — African-American women in particular — were key in recent elections that turned Virginia state government blue and re-elected a Democratic governor in Louisiana after President Trump campaigned for his opponent. Can Buttigieg solve this problem and save his chances to be the nominee?

And what does it say about the 2020 race on the Democratic side, which started out with such a diverse group, now that California Sen. Kamala Harris has dropped out and the slate for the December debate has narrowed to top candidates who do not reflect that party’s racial diversity. (Mary C. Curtis)
