Cheney's failure is not because she doesn’t like Donald Trump, that is the least important
part of this whole drama, but because she can’t do the job. Her job is to hold the caucus together and advance the Republican agenda. She can’t do it, and it’s all her fault. Her raging case of Trump Derangement Syndrome aside, she has fired down her own trench too many times. Leaders, effective leaders, don’t attack their own troops.
