No it's not.
The Enabling Act removed the power of the legislature. This is the exact opposite - the legislature still has power.
Only superficially: the dictator cannot be subjected to any judicial control, but the dictator’s party has a two-thirds majority on the top rung of the judicial system.
When you give the president additional power, the legislative loses some of its own power. The Enabling Act is just the most extreme example.
The President doesn't have additional powers in the Tiktok example.
The President has always been able to veto laws. Biden could have vetoed the bill if he wanted.
And a Congress that passes a bill that says the President has a say in it's execution isn't odd either. The administrative body always has powers of execution.
And Congress is free to pass a law to reverse the law and make Tiktok legal if they want.
Fair enough.
