We've all heard about the insurers that are pulling out of Affordable Care Act marketplaces, but sometimes you have to see it to really get it. This map is based on data from the Kaiser Family Foundation for the first four years of the ACA marketplaces. You can really see the difference in 2017, when high-profile insurance exits left 21 percent of all ACA customers with only one insurer in their area.

For context: This doesn't even count 2018, when there could be as many as 47 counties with no insurer at all. We'll have a better idea after this week's filing deadline, of course.

Why it matters: There are definite signs that the Trump administration's opposition to the ACA is hurting the marketplace for next year, as we wrote on Friday. But it's important to remember what was happening before the administration ever took office.

Senate passes bill funding government through December

The Senate on Tuesday passed legislation to fund the federal government through Dec. 11, by a vote of 84-10.

Where it stands: The legislation will avert a government shutdown before funding expires Wednesday night and before the Nov. 3 election. The House passed the same measure last week by a vote of 359-57 after House Democrats and the Trump administration agreed on the resolution.

  • Both sides agreed early in negotiations that the bill should be a "clean" continuing resolution — meaning each party would only make small changes to existing funding levels so the measure would pass through both chambers quickly, Axios' Alayna Treene reported last week. The bill now goes to President Trump for signature.

The age of engineering life begins

Synthetic biology startups raised some $3 billion through the first half of 2020, up from $1.9 billion for all of 2019, as the field brings the science of engineering to the art of life.

The big picture: Synthetic biologists are gradually learning how to program the code of life the way that computer experts have learned to program machines. If they can succeed — and if the public accepts their work — synthetic biology stands to fundamentally transform how we live.

Biden will allow lobbyists to join transition team

Joe Biden's presidential transition office will allow lobbyists to help shape his potential administration, but will require them to receive a waiver to participate if they engaged in lobbying activity in the last twelve months.

Why it matters: Presidential transition teams are instrumental in establishing a new administration, and the rules that govern them are often a template for the ethics guidelines that the new administration imposes after the inauguration.
