A Christian should not support (e.g., vote for) a government law that would restrict his freedom to exercise his conscience.
Do you know that the first demo(n)cracy recorded in scripture was the kingdom under Saul.
Saul was chosen by lot, (vote) even though Samuel anointed him.
1 Samuel 10:20-21 RSV
Then Samuel brought all the tribes of Israel near, and the tribe of Benjamin was taken by lot. [21] He brought the tribe of Benjamin near by its families, and the family of the Matrites was taken by lot; finally he brought the family of the Matrites near man by man, and Saul the son of Kish was taken by lot. But when they sought him, he could not be found.
Not so with David. David was a dictator who was never elected by vote.
Did you ever wonder about that, why so many people have a bee in their bonnet about dictatorships?
Did you ever wonder why the people voted after Samuel had already anointed Saul.
Do you know that a democracy functions on the selection of the one who is most highly esteemed by men?
Luke 16:15 KJV
. . .for that which is highly esteemed among men is abomination in the sight of God.
Did you ever wonder why democracy is the most esteemed form of government on Earth?
Hosea 8:4 KJV
They have set up kings, but not by me: they have made princes, and I knew it not: of their silver and their gold have they made them idols, that they may be cut off.
Have you ever wondered why a democracy only functions in prosperous societies and then as those societies degrade and become corrupt through democracy, they become lazy and lose their wealth and descend further and further down until the rebellion happens and the democracy turns into a dictatorship?
A Christian should not support (e.g., vote for) a government.
You got that part right and then you added to it and ruined it.
The word commands us to imitate only Paul and Jesus and they would never have voted for anyone, not just because that would be a stumbling block to those who did not agree with them, but for several other reasons revealed in scripture.
Do you know what they are?
