sorry you were confused with some of the content, I kinda rushed this last night but I'll explain you what those ones mean...
When I say the GOP was colonised by Trump, remember when the GOP was once a centre-right party. It was okay to be considered okay to be neoconservative, like many people voted Republicans because it had good American values which offers great capitalism policies, removal of some red tape, pro life views, and support of the second amendment.
Ever since George W. Bush was no longer POTUS, many Americans voted Democrats and ditched the Republicans because of modern life and fears that the GOP would go too right and it has gone too right. Trump basically took over the GOP and turned it into a Far-Right party when it's not Far-Right.
When I say it's too late to save the GOP, I'm saying its too late for Trump's MAGA movement to give up controlling the traditional Centre-Right party of the Republicans.
I understand why you'd vote Democrats but I'm not giving up my Fiscal Economics and Religious Right views but I can certainly sacrifice some more Right Wing policies so I can be seen as a transparent political supporter of the GOP.
