Think about it. There are still a lot of people who are asleep at the wheel about how bad establishment RINO "Republicans" really are.
Dems and RINOs and the media will side against MAGA and the will of the people and everyone will see Dems and RINOs taking the same side against Trump's endorsements. You can now see RINOs and the media flocking to prop up DeSanctimonious. Democrats will say stuff like, "Oh well I don't agree with DeSantis but I definitely see him as easier to work with and less volatile," and other such propaganda.
They will then openly see Dems, RINOs and the media all colluding to fight back against legislation or reforms or policies or investigations or whatever that they actually support, like honest investigations into Hunter Biden and his laptop, and will end up revolting and leaving those factions for MAGA.
In the end everyone (except 4-6%) will recognize and reject corporate establishment Dems and RINOS and embrace MAGA. All of the Democrat defects who are sick of what's going on in their party will join in on MAGA, and the Republican base will see the media they know and hate side with Democrats and RINOs against Trump and they'll clearly see something is very wrong, so they will join MAGA.
Enjoy the next 2 years. You're about to see just how much of a uniparty it really is.
Aged well indeed.
