If you are asking that question then you really don't know what principles are. No slight intended but your statement is a complete rejection of the concept of principles.
Matthew 16:26For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul?
Please do not take God’s Word out of context to try to support a political point.
The context of that verse is not dealing with a person who has to make a voting choice between two lousy candidates he/she would rather not vote for. The context is the whole world is not worth losing eternity in heaven.
People are not going to lose heaven over a vote. Not having Jesus as Savior and Lord denies someone heaven. The vote, you will have to give an account for, but you won’t lose heaven over it.
