It’s not a question of “washing of hands” but of biblical doctrine.
I am responsible to pay my taxes to the higher authorities. The government in turn is responsible for how they spend the money. Just like you are not responsible for the sins of your neighbor down the street, even if sometimes you socialize with him or even go to church with him, likewise I am not responsible for how the government allocates the funds they collect from me.
I can try and vote for moral people to legislate morally, that’s a responsibility I have, to use my spiritual discernment to pick the right people for office. But I am not responsible for the outcome of an election being different than I would like; nor responsible for the leader messing up once he’s in office, even if I voted in good faith for him and he happened to win. Any poor behavior or judgements on his part are his responsibility, not mine for having voted for him.
God sees and judges *individuals* at the different judgement seats, not groups.
