In most of the political-type speeches I see these days from folks running for election or re-election, I hear the candidate saying they have solid plans to fix a given problem or that they have incontrovertible evidence of some crime committed by their opponents…
…but they don't tell us much (sometimes, anything) about those plans or they don't divulge that evidence. It's always to be revealed at some future time and in most cases, it always will be. Donald Trump, for instance, has this wonderful health care plan that will replace Obamacare and be so much better and cheaper for everyone…and he has all these mountains of proof that he won the 2020 Presidential Election in a landslide.
I think we all instinctively realize that when a politician claims to have something like that and doesn't release it, it isn't what he or she says it is or, more likely, doesn't exist at all. I wish people — journalists, especially — would be more openly skeptical about such claims. I also wish the journalists would track them better even when they're made by people I might wind up voting for.
We should think of it like this: You're playing poker with someone and he announces, "I have a royal flush. I'll show it to you one of these days!"
