Jennifer Palmieri, who served as White House director of communications for President Barack Obama, gave her take on why white men are at the top of the early polls for the 2020 Democratic primary.

Palmieri had also served as communications director for Hillary Clinton's 2016 presidential campaign.

"It's something to see all the top of the polls being led by three white men, though. I have to say, you know, I'm concerned that, as somebody who worked for a woman candidate last time, that there's something that about the sort of biases we still hold about leadership and what that looks like. That makes us gravitate towards men and even white men," she said on Wednesday.

"That it is something about how we — this image that we still hold, makes it harder for the women candidates, who are really great, to break through," Palmieri said.

MSNBC host Andrea Mitchell devoted a segment on it after asking presidential candidate Sen. Kirsten Gillibrand, D-N.Y. about the issue on Tuesday.

"Why do you think white, male candidates are doing better than any of the women candidates," Mitchell asked.

"Well I don't know," Gillibrand replied. "But this is a marathon and not a sprint. And I know that I have a vision for this country and the experience to actually get it done and a plan to get it done."
