The quotes in this article supersedes whatever he said before because it is the most recent position he's stated (at least that I know of). And this last one is “government's gonna pay for it” which is conflicts with your quote from his book.
His positions change with the wind and you have to keep up... He's really sincere about it so lap it up. A little more socialism will make America Great again!
Kinda like Ted Cruz's immigration plan then. Constantly shifting in the wind.
