The fact that the legislator’s email was pure scathing sarcasm perhaps?
Doesn’t look like scathing sarcasm, doesn’t sound like scathing sarcasm, doesn’t say anywhere that it was scathing sarcasm.
All it says is that he said he was over the top, that there is no merit to his claims and that he should not have brought it up.
None of that means he was being sarcastic, nor does any of that means he doesn’t believe it despite the fact that it is an obvious political lie. He wants to promote it just like every other politician wants to promote it. He just isn’t used to being called on it, because no one ever calls them on it, so it looks to me like he knew he looked like a fool, just like they all look like fools.
I didn’t miss any sarcasm. Perhaps you should change your tag to (BlatantPropagandaLaughablyExposedDectorless).
Just a suggestion.
