Yes, the Vice President should reject electors which are clearly the consequence of a fraudulent election process, and he should do so, even if they are votes for his opponent.
Your position is “that appear to the President of the Senate, in his sole discretion, to be the result of fraud.”
Not one state alleged fraud nor submitted alternate electors.
