I don’t think another candidate has a stronger work ethic than Trump, based on his campaign schedule and interview appearances.
I believe Trump was destined to be President, all others can wait until there is another opening for the job, like take a number and wait until you get called Bush, Cruze etc.
Personally, I believe Trump is highly capable of being POTUS. His major fault is, although saying what we all want to hear, it is how he says things that I have the problem with. Any candidate can use plain English to get his message across, it’s the way in which Trump states his case that rubs me wrong, the words he uses is what rubs me wrong, Swearing does not make for a good leader, any more than shouting does. Trump needs to clean up his mouth and continue telling We, The People what needs to be heard.
