"Who would Jesus vote for?" is the wrong question. What you need to wonder is, what is God's point of view about elections?
God believes in working with whoever wins. The election of candidates is a concern of humankind. God attempts to work with everyone, both the winner of the election and the loser of the election, whether they believe in God or not. The Holy Spirit attempts to dialogue with everyone all the time (for example, even in the most Communist atheist governments the Holy Spirit attempted to continue its work with both the rulers and the individual people.)
All God asks for is clean, honest and peaceful elections without vitriol. God, "Jesus" and "Mary" do not "endorse" candidates.
(And so anyone who snooped who I voted for was totally wasting their time ha ha ha. Sometimes I vote for sheer perversity purposes...)
