CTL:
Any elector from any state can vote for whoever he wishes (even someone who didn’t run for office) for president and vice president even if his state regulations/laws say otherwise. This point is clearly enumerated in the federal Constitution, which overrides state rules on the matter. And there have been electors who voted against what their state rules permit, and they faced no consequence.
And the electoral college votes for both president and vice president. Any elector can split his vote however he wishes, and vote for the Republican candidate for president and the Green party candidate for vice president.
