What is worse is that “we” the people, allow that to happen. “We” keep electing the same people. “We” never hold our politicians accountable to the promises and statements they make. Take a look at your example person, Nancy Pelosi. She has been in congress since 1987. Think of all the things she has said, all the things she has done and not done, yet her constituents do not hold her accountable for her lies and promises. This is a story that is repeated time and time again across this country. I understand that incumbency has a particular advantage, and that once in power, a politician can change the rules to benefit them (again, to pick on NP as it was the example from the OP) take a look at the California primary process. So, until “we” the people wake up and demand more from our politicians, they will continue to lie, cheat, and steal, because there is no downside for them, no consequences. And when politicians are caught doing something REALLY bad, it reminds me of my 4 YO. You see them come out and make this big heartfelt apology, the scandal dies down, and next thing you know they are re-elected. Its like my 4YO who is in a phase who thinks that if he does something wrong and has a consequence, if he says sorry and acknowledges it, then maybe he can make the consequence go away. Well, “we” fall for it, time and time again.
