“he will—maybe unintentionally—break laws.”
Trump's political inexperience is obvious but all he needs to do is to surround himself with experienced politicians that are running the country already - and maybe listen to them, which seems to be the case from his remarks about Obamacare, etc. AS for breaking laws, all people in High Office break laws and get away with it, except when they happen to be an unpopular target -like Trump for instance, I say, give the man a chance. We will see effects soon enough.
