Would Mrs. Clinton have won in an alternative universe where the aforementioned alternations did not take place?
Which only demonstrates the supreme idiocy of the original system our founding fathers envisioned. Its a good thing they gave us a mechanism to change the Constitution and the rules.
The founding fathers never tried to design a perfect system. They only hoped to make a "more perfect" system, that over time would improve upon itself.
And improve itself it has. Vice Presidents and Presidents now run together, instead of being #1 and #2 in the Electoral College. Black people can vote (and be more than 3/5ths a person), slaves have been outlawed, Women can vote. This country is one of continuous self-improvment (or at least, ATTEMPTED self-improvement)
yes, and last presidential election was such an event.
And what, exactly, would that have changed?
Which means every "close call" vote in the Senate (including the Supreme Court Justice vote, various laws that have been passed this year, etc. etc.) would have only passed at the Pleasure of Ms. Clinton.
For another: Mr. Trump delegates a lot of tasks to the Vice President. The Vice President has a lot of power when it comes to implementing the President's policies.
So far, none of the above have been groundbreaking.
As for your last point: the idea that Trump would delegate anything to VP Clinton in the same manner he delegates items to Pence is utterly absurd.
