As has been said: climate change has been made into a new religion. Some extremely liberal politicians see woke ism being rejected, so their "changing party affiliations" or simply dropping out of the democratic party as a matter of survival, but are not changing their liberal ideology.
To beat a dead horse, Tulsi Gabbard is a prime example. She is now the darling of Fox News, but has yet to be confronted on her extremely liberal views, not has she herself addressed any of her past liberal transgressions. She hasn't joined the republican party, but is giving high toned commentary, and feeling things out.
She should have shown herself to anyone paying attention when she apologized to the queer community while running for election, then abandoning them when it was over.
ALL LIBERALS DO IT.
Liberals are camelions. They change when the need arises as a method of staying relevant.
