Having electors becoming free agents will open them to incredible bribes and threats. Voting will mean nothing.
I hope they decide that electors are beholden to the people of that state. An elector has the same voting rights as everyone else does. He goes to tje voting booth and casts his personal preference. But as an elector he should cast the will of the people, not his own. Otherwise he could vote twice. It condlicts with voting laws which only allows one vote per person.
And a couple, changing their State trends, could decide for the whole country...
