As far as Trump's promises about teleprompters or releasing his taxes, Trump supporters have found an array of reasons to dismiss these. The comments are usually "who cares?" Well, maybe the people who took his promises at face value?
Conway said since Trump was elected without releasing his taxes, the people said this was not an issue. The thing is he was elected with the promise.  He has violate that promise.
Now some will say, "well Obama said, you can keep your doctor" as a retort. That is true. But by invoking dismissal by hypocrisy they are saying Trump did the same as Obama. Meaning, they are comparable. They never notice this implication. https://en.wikipedia.org/wiki/Tu_quoque
