That article makes claims that are just not true. "Trump supported a decent minimum wage from the start, wants free education in state universities, has supported universal health care, consistently opposed the Transpacific Partnership Agreement and wants more bank regulation."

He very clearly is not in favor of free education, he is very clearly not in favor of raising the minimum wage, he very clearly is not in favor of universal health care, and very clearly is not in favor of more bank regulation.

So I find the claims that Clinton was more to the right of Trump quite dubious.

I think Trump has taken almost every conceivable position on every issue, so the claims in the article were presumably true for some particular moment of time.
