Iowa Democrats reported Monday that their biggest priorities were beating President Trump and health care — but the meltdown of their election reporting systems left their presidential choices unresolved.

Why it matters: We've been writing for months that Democrats have a major choice ahead, either picking an advocate of Medicare for All — and siding with the plan that's less popular with the rest of the country — or a public option advocate.

The Iowa debacle means the path the party will take won't be clear for a while longer.

By the numbers: Several polls — including ones by NBC News, the National Exit Poll and AP Votecast — found that around four in 10 caucus voters said health care was their top issue.

Previous polling has found that Medicare for All is less popular overall than a public option, but both were popular among Democratic caucus-goers last night.

Seven in 10 said they back a single-payer plan, and almost nine in 10 said they support a public option, per AP Votecast, which was conducted by NORC at the University of Chicago for The Associated Press and Fox News.

Yes, but: Caucus-goers said they prefer a Democratic candidate who can beat Trump over one that agrees with them on issues, CNN reports.

The big picture: Republicans are more than happy to talk about Medicare for All — and its subsequent tax increases and expanded government role in health care — instead of protecting and building on the Affordable Care Act.

Whereas the former gives them an opportunity to go on offense, the latter puts the GOP on defense against its 2017 repeal-and-replace efforts and ongoing lawsuit that would strike down the whole health care law, including its protections for pre-existing conditions.
