>> I do not think there is anything explicit in the law that mandates electors to vote for the candidate who won their state under all circumstances. (Correct me if I am wrong.)

https://en.wikipedia.org/wiki/Faithless_elector

As of 2020, 33 states and the District of Columbia have laws that require electors to vote for the candidates for whom they pledged to vote, though in half of these jurisdictions there is no enforcement mechanism. In 14 states, votes contrary to the pledge are voided and the respective electors are replaced, and in two of these states they may also be fined. Three other states impose a penalty on faithless electors but still count their votes as cast.
