Elections and honoring father and mother

Q: Must a child obey his parents if they ask him to vote for a certain political party?
A: No. ‘Honoring one's parents’ applies only when an act directly relates to one's parents. Honoring one's parents is giving them something to eat and drink, clothing them, covering them, and transporting them (Kiddushin 31b and Shulchan Aruch Yoreh Deah 240:4). If something relates to the child's private life – what he eats, what he wears, where he lives, etc… - this is his own business. This is also the case with if one wants to vote right, left or center – it is his life. Honoring one's parent is related to caring for them.
