What principles does a Christian violate by voting in a state referendum?

What principles does a Christian violate by voting in a state referendum on issues like allowing gambling casinos or legalizing abortion?

Voting, in and of itself, is neutral. If voting involves the believer in the political system, this seems to violate the principle of separation (Ephesians 5:11; 2 Corinthians 6:14-18). As our Lord Jesus, we are not "of the world" (John 17:16). He refused to be drawn into politics (Matthew 22:17-21). By our lives, we are to be salt, exerting a preserving influence on the world (Matthew 5:13). By our prayers, we are to effect good in government (1 Timothy 2:2). It is an admission of failure to have to use the voting booth to do what neither our lives nor prayers are doing.

On the other hand, a referendum, as stated by the question, may not involve entanglement in the affairs of this life (2 Timothy 2:4). Suppose a politician, for example, took a poll of neighborhood opinion and stopped at a Christian’s door. Responding would hardly violate the principles mentioned above. The same can be said of voting in a referendum.
