That's fair. Can you specifically articulate how she would be doing a better job?
All speculation since she did not win and not claiming she would be perfect or even close to it or without her own problems and controversies, but:
She would not be a complete and utter embarrassment.
She would not be asking a foreign power to dig up dirt on two American citizens.
She would not have felt the need for a Space Force.
She would likely be doing more to help middle class families across the board. This could be broken out into multiple line items.
I would not be overly concerned about her having access to the nuclear football.
She would not seriously consider nuking a hurricane.
She would have provided proper aid to Puerto Rico and the Bahama's.
She would not politicize disaster aid based on personal vendettas.
She would not be alienating most of our allies while catering to our rivals and enemies.
She would not demand that immigrants be shot in the legs to slow them down.
She would not be trashing the economy with an unnecessary trade war.
She would be unlikely to be running a trillion dollar deficit.
