You are right about this, in fact it is the crux of the problem. Our political leaders are too busy stuffing money in their pockets to be concerned about what is best for the country. Anyone who lives or works inside the Beltway are consumed with their personal wealth and their position relative to their friends, neighbors, and colleagues. They care not about the nation and our future. They will sell us out in a hearbeat, and we should not forget it.
I've often thought about this m'self .. that polits, as a rule, are only concerned for their own monetary well being and political power, that "Mr Smith Goes To Washington" is nothing more than a fantasy for the naive.
However, I *do* have some faith in the human spirit, and that faith isn't relegated to simply politics for politics sake.
Politics is a dirty game, always was, always will be ... its simply human nature, something that can't be changed ... the US Constitution took radical steps to make sure that politicians would be held in check by their fellow citizens, a system which has worked quite well for over two centuries.
The danger now is that an entire major political party has determined that they can flout the law and the Constitution on a regular basis, and go unchecked. This is what the Democrat party has become circa 2007 (and for about 3 decades now). It's a scary scenario, that one major party is willingly wrecking the Constitution, while the other major party isn't doing diddly-squat to counter it.
I fear for the future of our Republic
There is no "will sell us out" about it. Look at the southern border and what they tried to do with the ports deal. We ARE being sold out.
