You sound close to a #2. Irrational hatred. You probably think he’s Hitler or something.
I don’t think I could be fairly categorized as a sore loser because I am not upset at Trump due to my candidate losing. I have supported Cruz from the beginning and he is still in the race with at least a 25% chance of winning the nomination. If Cruz had lost, I would have been willing to support other candiates like Gov. Jindal, Gov. Walker, or even Sen. Rubio.
Instead, I oppose Trump because he truly terrifies and horrifies me.
