I dont have the post, but im sure about what im saying, you will have to trust me.
Once again it wasnt against your specifically.

Maxine Waters might be the only Dem Candidate that would be worse than Hilary. If she runs, I'll watch the news non stop for hilarity.

Could you imagine a Waters / Kamala Harris ticket? Oh the political debacle that would unfold.

the trend line comparison shows that trump is experiencing pretty much the same decline in popularity as all presidents in recent decades; he just started from a lower base.

i get the sense that those who still strongly support trump are dug in for the long haul, regardless of where that leads
so i don't really think support can go much lower
starting near rock bottom and staying there shouldn't be viewed positively as 'maintaining steady support'

a support of around 40% isnt great by any measure, but I also wouldnt call it "rock bottom". and no, I dont think his supporters will stick with him no matter what.

if he really messes up healthcare or if he starts a war and introduces a conscription, or if a really big scandal comes up, or if he breaks with his anti-immigration stance, his core supporters might leave him.

in the following article, bottom third, under the headline: "Immigration: Opening the door":
https://fivethirtyeight.com/features/three-things-trump-could-do-to-hurt-obamacare/

if thats a one time thing, its no big deal. but if trump really changes his position on immigration, I think that is something that would really not go down well with his core supporters.

Nnnnnoooooooooooooo

Dems need to nominate a White Anglo Saxon Protestant who isn't a gun grabber. Or Trump will get a second term.

Ayatollah Elizabeth Warren for 2020 ?

Too white IMO
