Yeah, election promises and post-election behavior aren't really correlated in general. I think this administration is worse than the average, but still.
Past talking points are not indicative of future behavior.
They're generally fairly correlated?
Lots of politicians fail to deliver. This administration just flat out lied about their priorities.
It turns out there is extensive research on this, and you are mistaken. Most politicians actually do try to deliver on their promises. They might get stopped, but they try.
https://strathprints.strath.ac.uk/59403/1/Thomson_etal_AJPS_... for one quick to find example of the literature on this.
Most of the research on this was done before Trump entered office. Trump is a wildly unusual political leader, who is significantly more corrupt than other politicians, promises random things and then fails to deliver them, and generally breaks all of the rules that politicians follow- this is what his supporters describe as his "authenticity", that he "tells it like it is". The more people believe, incorrectly, that "all politicians are corrupt" and "no politicians deliver on their promises" the more likely they are to accept Trump- who again is an extreme outlier among American politicians.
Your cynicism actually ends up ruining the country and makes it more likely that we have bad government.

when will we make it illegal for a politician to lie
