Like it or not, the Bible says that God decides who the leaders of humanity will be. So, I try not to spend time worrying about it.
"Don't worry about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus." (Philippians 4:5-7)
We are told to pray for all people, and specifically our leaders...
"I urge, then, first of all, that petitions, prayers, intercession and thanksgiving be made for all people— for kings and all those in authority, that we may live peaceful and quiet lives in all godliness and holiness. This is good, and pleases God our Savior…” (1 Timothy 2:1-3)
Following is what the Bible says we should think about, and it is not politics or religion...
"Finally, brothers, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is admirable—if anything is excellent or praiseworthy—think on these things." (Philippians 4:8)
