As Alarcon notes, it's the author of the article who says those things.  But the article is a wee bit strange.  A former journalist for the WSJ talks about being liberal, yet believes that Trump and his supporters were unfairly demonized.  I have heard many say that they can't "afford" healthcare under the ACA, but then, upon closer inquiry, I have always found out that it was simply that they did not want to pay for health insurance, because they could get away with not doing so.  Quite frankly,  I don't understand what mother (she calls herself a "single mother" at age 51 (I wonder how old the children are) would not want health insurance.  
The story reminded me of the saga of Joe the Plumber.  Many things about it sound off.
