The GOP establishment has made it clear that they would rather have had someone else as president instead of Trump - even Hillary in some cases.
They see him as an intruder; a usurper of their party leadership, and an unwanted reformer of their perfectly satisfactory “Good Old Boy” system.
Don’t you wish they had stood up to Obama’s profligate spendthrift ways as strongly as they are standing up to Trump’s request for small seed money to start building The Wall?
As long as Trump is president they have no loyalty to the party platform, to the party or to their own president.
They want Trump out of there in 2020.
Between now and then they are not going to do anything voluntarily to make his administration a success.
No wall, no GOP. No peace.
