No. TH ywere choses as electors under false pretenses. They must go too.
Obama may have committed the largest case of voter fraud in history, but the Electors are the Electors and they cannot be "de-elected". They may or may not be prevented from performing their duty due to the actions of others, but they, themselves, have committed no wrongs.
Here is a nice discussion of the role and responsibilities of Electors, and some interesting history. Note the discussion of faithless electors and examples that might apply (substitute "removed" for "died" as I expect the mechanics will be essentially the same if Obama is removed from the ticket).
