1. Border Wall. ... The Republican Party has had no interest in securing our border -- ever.

2. Investigating Clinton (Lock her up) ... Trump himself was already walking back that promise within hours or days of his election in 2016.

3. Complete repeal of ObamaCare. ... That had nothing to do with Mueller. The GOP (as I predicted in 2010 when it was passed) never had any intention of repealing ObamaCare. Heck -- you can't even find a majority of FREEPERS who would support a complete repeal of ObamaCare.

The results of enacting his policies speak for themselves. What does a 55-60% approval rating make possible? Does the House flip?
