House Democratic Leader Nancy Pelosi likes to say that “beauty is in the mix," arguing that diverse viewpoints lead to a better debate and stronger policy outcomes.

Why it matters: If Dems win back the House in November's midterms, as expected, Pelosi will usher in the most diverse leadership team (in either chamber) in the history of Congress.

Half of the 22 committee chairs would be women or minorities — or both.

The chart above shows the projected chairs. In most cases, it's the ranking member (top Democrat) of the current committee; Pelosi has said all of those members are expected to move up.

In the case of retirements (two), this chart shows the next member in seniority, who is expected to get the job.

What a change this would be: The current Republican chairs are all white, with two women.

House Dems are now 41% white male, which is sure to fall in the next Congress, with November's record lineup of Democratic nominees.
