If you have any doubts about the US and need to find a way to alleviate those doubts, then the Constitution first and foremost should be your guide. They're the principles that everyone who immigrated here agreed to abide by when they became citizens. So... which actions and behaviors of the current politicians are aligned with the Constitution? Which ones are not? That's really all you need to know. Then start rooting out the ones who have no allegiance to this country and are willing to drain its physical and financial resources and let it take the blame for the atrocities they commit while never abiding by its Constitutional principles in the first place. My country has been subverted, but I am not willing to throw out the baby with the bathwater.
