You do realize that a non-trivial amount of politicians have publicly made similar claims about the Jews? It's not like this is some isolated incident.
And these are just the outright ones, there is plenty of this stuff at rallies and protests that help fund politicians - there are hardly any condemnations unless it's so blatant it hurts their war chest.
Sen. Wendy Rogers's quote was not about Jews at all. It was about latino migrants (not that that's better).
Ron DeSantis spokeswoman isn't, what I would call, a politician - and her quote was specifically about the Rothschild family. Although it's not clear which conspiracy theory she's refering too - many of them (while all irrational) are not anti-semitic. It also doesn't seem to be a serious comment.
Your other two links are for a candidate, not an active politician.
There is no direct antisemitism, only some sort of wink-wink dog whistle accusations.

Demographic concerns are common across the world (https://en.wikipedia.org/wiki/Demographic_threat). There is really nothing special about it. And there are always fears of "voter importation". It is not comparable to "Jews want to exterminate others with vaccines".

I guess if he weren't Jewish, he would also be accused of antisemitism because he mentioned Soros? Thankfully for him he ticked the right box when he was born. And yeah, this seems to be the only person who openly articulated conspiracy theories. But again, that's your run-of-the-mill "deep state is puppeteering social movements to keep power", it doesn't look like "similar claims about the Jews".
