The only power congress theoretically has to impact the administration is that of the purse.

But the admin has repeatedly ignored such restrictions. This check on power also loses it's teeth when the oligarchs align themselves behind the executive branch.

Remember? ... Memories have a price. Nothing's changing any time soon while the elected represent money, and paid-for interests.

Of the dollar, by the dollar, for the dollar ...

The well-actually testicle TED talk misses the point. Representatives have power, and sometimes that power is for sale. And that position to represent was also for sale. As was the attention of the electorate.

Honestly, calling Congress castrated is fine because it is healthy venting about how ineffective they seem at their charter.

Even though it's really charming and compelling to believe, there is no one solvable problem simply requiring elbow grease, voting harder, proprioception of comically vulnerable reproductive organs, etc.

The framing that congressional politicians have "forgotten" that they have power is a silly and dishonest trope. They absolutely know that they have power, but they also just watched multiple incumbents (Cornyn, Cassidy, Massie just to name a few) who didn't get Trump's endorsement lose their respective primaries, effectively ending their political careers.

Members of Congress, just like everyone else, act in their own self-interest. And unfortunately for pretty much everyone else, their best method of self-preservation is to do nothing, hence the "eunuch" Congress.
