I do not believe cynicism is entrenched in our society so deeply that it is the matter of course. I would say it's the exception generally, with somewhat more prevalence in politics.
But, as it seems you assert, it is entrenched in MAGA (where the ends justify the means as well). And, unfortunately, the saner majority of Republican politicians are going along with the cynical MAGA wing of the legislative branch (mostly in the House). I think it's due to the error inherent in social media distortion, but I digress.
So though the House Republicans are not en bloc cynics, they acquiesce. This is from where originates my concern and suggestion that a drop-dead date is worth considering. I think it would be considered by the Democrats, not as a cynical ploy used exclusively to maintain power, but to inform the use of available tools to preserve our liberal democracy!
How it applies to, say, GA lies in the inherent uncertainty of an election outcome, specifically the 2024 election.
Do you disagree that the Democrats would consider it?
