This is an ABSURD discussion.
Just use the “upside or downside” rule.
Is there an upside for dumping Pence? NO!
Would there be a downside for dumping Pence? ABSOLUTELY YES!
Would ANYONE believe that Pence “just wanted to spend more time with his family”?
Unless Pence drops dead or gets an aggressive debilitating cancer, he isn’t going ANYWHERE!
SHEESH!
Remember, the VP spot can only HURT you, it never really “helps” you.
Boring is good.
Make no waves. Attend those funerals, cast a tie breaking vote, and be ready to take over if needed.
That, is the sum total of your job.
