OPSEC
Trump won’t let on about certain key issues because they are sensitive in as much as timing, security and such, and no amount of weaseling by the MSM will get anything from him.
When he is ready, he will pounce with things that we are wanting answers to, but now is not the time, why give the other candidates his ideas to run on?
The only other two candidates he will embrace is Cruz and maybe Carson...I think the three of them have been talking privately for some time...and I think you'll see a threesome before long...
The rest of the candidates aren't doing anything, and I don't think Jebby will ever be a problem...remember the American people don't want any more bushes, clintons or obumas....
As far as Trump attacking, why not? If someone attacks you, do you go running in your hole? I don't, I face it and say what I feel, he's doing what everyday normal people do when faced with lies and slander...and Fox had better be really careful, Trump has already filed suit against Club for Growth...he can do it to Fox to....
