Why are establishment Republicans so afraid of Donald Trump winning the nomination?

He doesn't have any good ideas. He wants to build a giant wall and make Mexico pay for it, but how is he going to do that? He has no specific plans.

I also find him immature and unfit to be President.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
