I say he did not lie because I feel they actually believe their plans and policies in the best case scenerios or what their staff tells them how to sell it. When Bush said "No new taxes" I also feel he believed it at the time. Things change or private sector reacts to the law a way any normal industry would but it is never considered.
Now Trump...he certainly lies knowing full well in advance that Mexico was never going to pay for the Wall.
The problem with ACA is simple, it mandated coverage for many people who could not afford it and also forced companies to stop bumping people from pre-existing conditions. Ok great ideas to spread health care to those would have otherwise been denied coverage, but someone still has to pay for it. So no surprise health insurance companies changed the plans being offered and raise premiums/rates.
Simple economics, you want it, you pay for it. You cannot pay for it, well someone will still pay for it.
The only thing that was meritorious was the attempt to fix the pre-existing condition situation where companies would deny you coverage because you already were sick.
They're not the same. Obama lied and he knew it when he said it. With Bush, he was persuaded to change his views. Like you said, Bush believed what he was saying when he said "no new taxes". When Obama said "if you like your doctor/ins, you can keep it" he KNEW it was a lie. And as far as Trump's lies go, name one that has cost me a dollar.
