Other races, lower classes and LGBT.

Republican's only need their voters to be two things:

1. Hates one of the above.
2. Doesn't give a shit about the other two.

So they are incentivised to scatter shot and hurt as many people as possible to get the maximum number of votes... America is fucked.

There’s no checks and balances left,

There is one left, but we're not allowed to talk about it.

Yes. Simple majority is all that's needed in the House on most if not all matters anyway. And the only thing that would be in the GOP's way would be the filibuster, which they can hand-wave away any time they want with a simple majority vote.

And keep in mind. They can just make up the rules as they go along now. They can literally play Calvinball with the Constitution. If Trump demands it, and the House and Senate vote for it, and the Supreme Court rubber stamps it, and the majority of state governments either go with it or at least don't oppose it.....who's gonna stop them?

If Trump feels like saying that the 14th no longer applies to brown people because fuck you that's why, and Congress votes in favor of a law that says the 14th no longer applies to brown people, and the Supreme Court says "Yep, fuck brown people.", then that's the law of the land regardless of what we think of it, because we individually do not have the power to stop it, and collectively just voted in favor of it.

And keep in mind......there's nothing stopping Trump from replacing "the 14th no longer applies to brown people" with "Women no longer have the right to vote" or "Freedom of the Press does not apply to those critical of the Trump administration". If no branch of government is willing to uphold and enforce the law, the law may as well not exist. The same goes for your rights and protections.

Those Democrats have careers and families they care about. It doesn't take much pressure to own a few of them. Especially without checks and balances and add in some bootlicking appointees to the three letter agencies.

I've only heard that applied to foreign diplomats. Because the parents have diplomatic immunity, they and their children aren't "subject to the jurisdiction thereof."

If they aren't, then border patrol would have no grounds to detain them. ICE could not deport them...

"Actually, we find that the 14th amendment really only applies to foreign white people, as the original founding fathers were slave owners who did not view either black or native american people as actual people, and certainly would not have granted them citizenship. Given the original intent of the Founding fathers, not only do we rule that the 14th amendment only applies to foreign white people, but we are simultaneously invalidating the Civil Rights act of 1964, reversing the previous Supreme Court ruling in Brown vs. Board of Education, and striking down the 19th amendment as an unconstitutional violation of the original intent of the Founding Fathers."

-- This supreme court, very possibly.
