I wish there was simple three strike policy on any elected official. Three proven lies and they are remove from office for life. And these can be anything. And not knowing at time does not change it.
Only silence or absolute truth should be accepted.
That's how it works right now. Besides Trump, the US's last presidental impeachment was over a sex scandal. They "say" it was because he lied about it, but I think we know better at this point. It's just really hard to impeach because you need 66 or 67 of the Senate to agree on something, not the usual 51.
But yes, we'd need some truly neutral Ombudsmen to back up such a system. And they themselves would need to be accountable should they corrupt. I don't think it's impossible, but hard to do with the current power structures.
"absolute truth" doesn't exist. I understand what you're saying, but the question of when a lie should then disqualify you from office must itself be a political question.
Absolute truth exists, and a claim that it doesn't is self-contradictory. The difficulty is in determining what is or isn't true, especially for empirical matters. (In math and logic the difficulty can vary. And some statements are true by definition, e.g., all unmarried men are bachelors.)
You're confusing logical/mathematic "truth" with philosophical/scientific "truth". While "politics should be based on scientific truth" is an opinion I have some sympathy for, even if it immediately falls apart under any scrutiny. "politics should be based on mathematical axiomatic truth" is a statement so laughable I can only imagine you forgot the context we were talking about.
P.S. I'm not confusing anything and not forgetting any context, and then I get slammed with an absurd strawman, "politics should be based on mathematical axiomatic truth"--not remotely anything I said. Gawd but some people are rude.
The fact remains that absolute truth exists ... "delusional" seems to have no idea what the word "truth" even means.
Only silence or absolute truth should be accepted.
