Washington (CNN)Poll of the week: A new national Monmouth University primary poll of voters who identify as Democrats or lean toward the Democratic Party finds that former Vice President Joe Biden leads with 32%. He was followed by Massachusetts Sen. Elizabeth Warren at 15%, Vermont Sen. Bernie Sanders at 14%, California Sen. Kamala Harris at 8% and South Bend, Indiana, Mayor Pete Buttigieg at 5%.
What’s the point: Biden’s advantage is being powered by African-Americans. Although Monmouth didn’t breakdown voter choice whites and blacks, we can look to other surveys to see how well Biden is doing with black voters.
An average of our CNN polling in late April and late May shows Biden lapping the field among black voters with about 50%. Harris, Sanders and Warren were all between 5% and 10%. Biden’s 40 point lead among black voters was more than double his about 15 point lead among white voters.
Biden only has endorsements from five black Democratic members of Congress. That’s only 9% of the available endorsements from black Democratic members of Congress. This suggests that black lawmakers are not sold on Biden’s candidacy.
Harris trails among this group with three, but she may have some momentum. This week Harris got the endorsements of both Rep. Al Green of Texas and Rep. Alcee Hastings of Florida. These were her first two endorsements from black members of Congress outside her home state.
It’s also noteworthy that this race has gone on for nearly half a year now, and there is no sign that Biden’s support is ebbing. Neither Booker nor Harris seem to be catching on yet with voters.
In other words, it was pretty clear at this point that Obama was appealing more to black voters than to white voters. And after winning in the Iowa caucuses, Obama was able to fully capitalize on his appeal.
This year it is Biden, not Booker or Harris, who is showing the same trend of doing significantly better with black voters than white voters. Additionally, it’s far from certain that Booker or Harris will come into South Carolina with any early contest wins under their belts. Neither have broken out of the single digits in Iowa or New Hampshire.
