You have some issues you need to work on there, Hank. Aside from your attitude, though, I don't think your basic argument holds water. Strength comes in many different forms, and Trump isn't as strong as you seem to think. Moreover, a lot of people will be casting anti-Trump votes specifically, and unfortunately they won't be going to the likes of Gary Johnson or any other third-party candidates.
Hillary doesn't often play the I'm-a-poor-little-girl card, and she'll be promoting her strengths as a politician with experience, whereas Trump comes across as an insecure billionaire with no political experience. There are, unfortunately, a large number of voters who see Hillary as being politically much stronger than Trump, and often his particular brand of crazy makes him appear much weaker than he probably is.
Regardless of whether it comes to down Trump vs Hillary or Trump vs Bernie, a lot of people will be casting anti-Bernie, anti-Hillary, and anti-Trump votes. When you have an election with such terrible candidates across the board, this is what people will be doing, not rushing to Trump because he's a man and a big talker. You'll have people who see Trump as strong, Bernie as strong, and Hillary as strong, but most people will probably be casting anti-candidate votes this election.
