Ah, but until that MAN returns He expects at least a remnant to be winnowing the flames of what RIGHT is all about, and that would include casting a vote for a person who is at least advocating the RIGHT.
Actually, He expects His remnant to preach the gospel in and out of season, to be hounded and scorned, to be hated because they are not of this world, and eventually to be crucified upside down in Rome as a witness to His resurrection.
There's nothing in John's gospel or in Acts to suggest that He has any interest whatsoever in Christians as Christians taking the slightest interest in politics.
