Dems will run on healthcare, wealth inequality, climate change, and maybe expanding voter rights & reducing dark money in politics. If they're smart they'll run on trying to give a bigger paycheck to public school teachers in k-12.

Like I said, dreamers is less than 0.5% of the US population. It's a morality issue and that's about it. It won't be a priority but they'll probably do something from just DACA with USA act all the way to comprehensive immigration reform. During the campaign, I don't expect them to talk about DACA much because there's a lot of other things to talk about. However, if they're asked about dreamers they'll say "I'll support dreamers" or something along those lines.
