I say that involvement with politics is not something that a believer should even bother with, given these commands:
" Thou therefore endure hardness, as a good soldier of Jesus Christ.
4 No man that warreth entangleth himself with the affairs of [this] life; that he may please him who hath chosen him to be a soldier." ( 2 Timothy 2:3-4 )
" Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?
15 and what concord hath Christ with Belial? or what part hath he that believeth with an infidel?
16 and what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in [them]; and I will be their God, and they shall be my people.
17 Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean [thing]; and I will receive you,
18 and will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty." ( 2 Corinthians 6:17 ).
"Love not the world, neither the things [that are] in the world. If any man love the world, the love of the Father is not in him." ( 1 John 2:15 )
With the above stated, I stopped voting years ago due to being clearly outnumbered.
I also now see that my vote for God's ways really makes no difference, as most people aren't ruled, in their consciences, like God's children are.
The saving grace in all of it is that if God wants a nation to go a certain way, He will raise up politicians that will make and enforce laws that keep the peace and that ultimately results in what He wants, being done.
Since most of mankind is at enmity with Him ( except those of us that are saved ), my own personal conviction is to stay out of their way, pray that God's will be done and for the leaders of my nation, and leave the rest to Him.
However, if any of you feel led to stand against something, then do so.
I can only tell you why I don't get involved anymore, and it has to do with separation.
