I'm going to say a thing that would be considered entirely reasonable if we were talking about any other profession, but since we are talking about the powerful, will be disregarded:

That is not my job. That is the president's job. I should not be expected to come up with a strategy to solve their problems. When they tell me they are going to do something, and then fail to do so, they did a bad job.

I used to think like you do. I used to think I was savvier than all the naive people who wanted things from their politicians, and criticized the politicians when they didn't deliver, because how could they have? But over time I've realized that I was being duped. That I should stop arguing that better things aren't possible, because when people believe that, it comes true.

A criticism I'll head off: I understand I can't vote for them and forget it. I'm not advocating for reduced civil engagement; it's our job to protest and agitate.
