She has also been very adamantly against what Israel is doing in Palestine, being the first republican representative to call it a "genocide"
Some claim this is because she is anti-Semitic, I personally think she got tired of being passed over for cabinet positions while her own party argued if she was a "trans woman."
I think she's trying to create her own little branch in the GOP now, and it looks like she's going full woman power. Which, hey! If it gets shit done, and she actually helps these SA survivors, fucking awesome!
I don't think it's a "rats leaving the sinking ship" scenario so much as she sees a potential power vacuum happening and she's making moves that will make people on both sides happy
