Trump losing GOP conservative base
Trump spurs some top conservatives to step back from GOPThe irony is that they are as frustrated as the Trump voters are with the refusal of Congressional Republicans to fight the evils of liberalism being pushed by Obama and Harry Reid. They do have a deep distrust of Trump. When you believe that both Trump and Hillary Clinton are dishonest, not voting for either is a realistic option. There is a belief among conservatives that both Clinton and Trump are unfit for the office of President.
The core of their resistance has been a calculation that they would rather preserve their ideology than promote a nominee who they believe would violate their ethos.
