Saw a recent poll, that didn't have healthcare very high up on the list of concerns for voters, guess they think ACA is "settled" now, but it is most definitely not.
Dems can never win on the border or economy, for various reasons, but this one they have won on before, and can do so again, they should shout out every day that Trump and GOP are coming for healthcare again, which they are, Trump still promises to overturn ACA.
Healthcare, abortion, democracy, and to some extent, economy, are the issues dems should run on, they should not waste much time on the border.
