Oh, I think the apathetic public does indeed give a damn. Most are just sitting around bidding their time until his term(s) up. From what I can tell from associates, co-workers, even people in the pub, they're pretty fed up with Tweet-storms and BS coming out the White House.
And he probably will get a second term as the Dems are destroying each other instead of focusing on their target next year. It is apparently true in politics that the squeaky wheel gets the grease and Trump squeaks the loudest and more often then the others.
