The man's deeds are what should give you doubt. He is a huge employer of illegal aliens. He voids promises repeatedly. He socializes and has supported the socialist causes and operatives conservatives oppose, including Bubba.
Other than that, there's nothing to worry about.
Haven’t contribute one penny to Trump and am not defending him from his many attackers, of which I am not one. He’s doing well on his own.
Trump is not bad-mouthing either Cruz or Palin and for that I am grateful and won’t bad-mouth him here on FR or anywhere until and unless DT does.
The nomination is a year away. The election is MORE than a year away. Things happen in that amount of time.
Try to enjoy this Trump performance and not worry as much about him?
