If a story has not had significant attention in the last year or so, a small number of reposts is ok. Otherwise we bury reposts as duplicates.
It's nothing to do with it being political. It's simply to do with being a duplicate of a story that has already been heavily discussed, just a week ago.
It's a well established convention that a topic is only eligible for further front page exposure when there is "significant new information" (SNI) [2].
There have been many instances of SNI with respect to DOGE this year, which is why there have been (I believe) more front-page stories about it on HN than anything else [3].
