Than you, and everyone else that isn't running. You PROBABLY would be a better candidate, as would almost anyone else. However, by rule of participation, he is automatically a better candidate than anyone who doesn't run(the argument can be made that no President is better than a Trump President, but that doesn't fit my narrative, so quiet).
Everyone's a critic, because it's so much easier to be a critic than to act on what you say. The loudest critics of your direction are generally those who never reach to get what they want. This could be external, but way too often, it's internal. Worst case scenario, we are telling ourselves that something won't work before giving it a chance.
When presented with something new, or different, is your first reaction to think of why it wouldn't work? Are you setting yourself up to fail, without ever trying? Are you letting the Donald Trumps of your world get opportunities because you aren't even participating?
Don't get beat by the Trumps of the world. Show up.
