> Ask yourself this question: who has made more important, far-reaching decisions for the country, Mitch McConnell or Barack Obama?

Oh, so you aren't asking which institution is more powerful, but which faction is better at using power, the currently dominant faction of the Democratic Party or the currently-dominant faction of the Republican Party?

> Repeat the same question with Trump or Biden if you want, even though they have left time in office than Obama.

Considering all four, considering impact and not positive/negative polarity, and considering that in some cases certain of the decisions at issue involved both institutions, and weighting for time in office since we are assessing the power of the institution not the power a person can exercise over their tenure in the institution, my initial impression is Trump > McConnell > Biden > Obama, though that might unfairly promoting McConnell and/or Biden.
