Judging from your name, I think you can count and would be a good exercise for you to count the number of states and federal offices that were won in 2014.
Your knock on Cruz is that his efforts, for example, on Obama Care did not result in repeal therefore he accomplished nothing. That is your test. By that test Trump has done nothing, he did not enter the arena, he did not run for office, he did not publicly support Ted Cruz in his efforts. Having left Cruz unsupported, he now leaves his supporters unrebuked as they attack Ted Cruz for not succeeding.
If it were not alleging guilt by association, I would accuse Trump of hypocrisy; or perhaps there is a legitimate criticism to be made for Trump's failure to repudiate these attacks on Ted Cruz while his adherence claim credit for him for what Cruz is done.
I have refrained from commenting on your APA attacks which require a whole series of lengthy responses. I will simply say that Ted Cruz's position at the time he voted for APA was a perfectly valid conservative position endorsed by the Heritage Foundation, consistent with the economics preached by conservatives like Milton Friedman, and absolutely necessary if any treaty or agreement were to be negotiated. His position was quite open and when circumstances changed, Cruz openly changed his vote.
