It's very easy to write up position papers; anyone can do that, or can buy them, just like you can buy term papers online. The problem with Trump is his track record, his history. His is very inconsistent and doesn't demonstrate a commitment to those position papers. I like a lot of what he says, but I just don't trust him.
Like any election, it is going to come down to a judgment call on the part of the voters.... examining the "puts and takes," the "pros and cons," of each candidate in isolation, as well as compared to the other candidates in the field. It should remain a fascinating process to observe!
