Politics is simply not the way to make change, they said. Two-thirds of nonvoters agree, for example, that voting has little to do with the way that real decisions are made in this country; they are 21 points more likely to say so than people who voted.

A majority also said they believe it makes no difference who is elected president and that things will go on just as they did before. Nonvoters were 29 points more likely to say that than people who voted. (Read more about why they didn't vote, in their own words.)

And

Nonvoters are also more likely than voters to say that traditional parties and politicians don't care about people like me; the mainstream media is more interested in making money than telling the truth; the American economy is rigged to advantage the rich and powerful; success in life is pretty much determined by forces outside our control; and to feel that most issues discussed in Washington don't affect them personally.

The article already says NC voted trump the last two elections, and I already quoted it...

So I'm going to assume you don't need another source for that

Benefit of the doubt that's true and he did get some stuff done that was substantial:

Is it enough to offset alternating with Republicans?

Moderate progress only works if it's steady. Ten steps back and five steps forward is still moving backwards.

If moderate progress is the most we reach for, we'll never make any progress on a long time scale when modern Republicans get equal turns.

And the way to prevent that, is trying for faster progress. The party just won't try that, because their donors don't want it.

Bringing us alllll the way back to 1/3 of voters just not voting.
