Biden on why he thinks he has more support from black voters than Mayor Pete

• "If you take a look at why he doesn't have support in significant black support, even in his own city, his own city."
• "I come out of an environment where I have the eighth largest black population in the country, in my state, and that's where I got my political education."
• "A lot of people have not spent a lot of time in diverse communities. I have, I have. Including in the Latino community."

Earlier in the interview, Biden referenced his history in the African American community:

• "I've never been uncomfortable or unwelcomed in the African American community. And because they know I care deeply about the issues ... that affect them and systemic racism still exists."
• "I've been deeply involved in the issues that we used to call and still affect civil rights and human rights."

The big picture: Biden has consistently polled very strongly among African American voters, while Buttigieg has struggled to make inroads.

• This will become a real problem after the Iowa and New Hampshire primaries, which feature mostly white voters.

The bottom line: Despite several candidates surging at times in the race — first Sen. Kamala Harris (who dropped out last week) and then Sen. Elizabeth Warren — Biden has led the RealClearPolitics polling average for all but a few weeks of this primary cycle.
