The final Obamacare exchange numbers are out — 12.2 million people enrolled in a plan for 2017, down from 12.7 million sign-ups last year, according to the Centers for Medicare and Medicaid Services.

The percentage of these enrollees who are ages 0-34 remains unchanged from last year at 37 percent. This is the key figure health wonks were watching, as more young and healthy people in the marketplace is likely to stabilize it and drive down premiums.

Not surprising: These numbers are somewhat expected. Not only was outreach depressed during the final days of open enrollment, but the Trump administration took power during this time promising to repeal the very exchanges people were enrolling in.

A producer from the Commission on Presidential Debates will manage the operation of the candidates' microphones during Thursday's final presidential debate — not the event's moderator, NBC's Kristen Welker — a source with knowledge of the event told Axios.

Our thought bubble, via Axios' Alexi McCammond: Given President Trump's accusations of partisanship against the other debates' moderators, it makes sense that Welker would want to steer clear of any such optics during her stint in the chair.
