That's all very interesting about the Electoral College, and if you read the whole article, you'll see a lot about polls about "approval" of Trump, which are used as a proxy for how people will vote. But in an election, you have to vote for one or another candidate (or abstain), and you might disapprove of all of them.

That is, withholding approval doesn't mean you won't vote for Trump. It's hard to approve of Trump. He's not exactly approval-seeking. You might like the results he's getting and still feel you want distance from him. You might vote for him because you want more of the same or because you think his opponent will take away some of the things you like and still be able to say that you "disapprove" of the person known as Trump.
