Interesting. Some merit there.
One thing though, Trump has been writing books since 1987, since before conservative books have been in vogue, and he has written dozens since then.
Most of his books have been business books (technically, more like motivation, ra ra type books), not political. His last political book, The America We Deserve in 2000 took a very populist, down the middle bent to it and had a lot of very liberal positions on issues (documented on many threads here), reflecting the 50/50 split in the country we saw at the time (later reflected in the Bush v Gore race). That actually reinforces the point I was making about simply positioning himself ahead of cultural/pop trends, not actually reflecting true held values.
Even with his business books, you can see the same positioning ahead of pop culture trends. In the 80s, The Art of the Deal came in line with the M&A boom and deal making was the rage. Later, in the 90s, How to Get Rich focused on start ups and capital acquisition right as that was booming in the newly emerging internet venture capital boom. In the mid-2000s he went to town writing books (ok, putting his name on books others wrote) all about 'thinking big' and 'think your way to riches' at the time when The Secret, What the Bleep, and other believe your way to prosperity programs were taking off.
It is all positioning, and as soon as the tide turns on an issue, he'll take a different position as he always has.
