I don't really consider it backtracking...he's squirming.
He knows he can't abolish Obamacare totally because people will be up in arms even more...and rightfully so. It has it's flaws, but it has helped a lot of people also...and he really doesn't have a concrete plan to implement for replacement.
He can't throw Clinton in jail, because she's been proven innocent.
He's not saying anything more about mass deportations and mouthing off on Twitter because his advisors are trying to calm shit down and prevent him from getting shot before he even takes office.
The wall...probably won't happen, financially and geographically going to be pretty damn hard if not impossible. Maybe he'll wall of sections, that's about it.
Basically time will tell. He has a bigger team of advisors and people working with him now to help reign in some of the stupid, so now we wait.
