Methinks u need to research what flip-flopping actually means in the political arena.
Hillary has stood up and clearly stated her position on something and then at a later date has taken the exact opposite position. Thats called flip-flopping. Google "hillary flip flopping"... hell, put it in Youtube. You will see its a clearly accepted fact that Hillary is a flip-flopper, always has been and always will be.
Trump is incoherent and a mess... he has totally different issues.
