If you are still undecided or not sure, just look all around you. Your prayers have been answered.
For example if you think everybody should haves access to healthcare. Seek and you will find which politician who will support your views. Otherwise chose those who say everyone has to pay his own medical bills and no medical benefits for those who cannot afford.
Some political candidates say they can cut costs while increasing jobs. Basic economics says this is not possible. Only spending from the public and private sectors can increase employment rates. Here is an example how politicians exploit those who are not educated.
Beware when they say everyone should pay the same tax rates. The poor and even the working poor living below subsistence and in need cannot pay the same tax rate and millionaires. Be careful when speech that sounds fair it is actually not fair.
Beware of politicians who are supported by religious institutions or misguided religious views to support powerful interests and remove basic rights from silent groups. There is nothing godly in denying other the basic rights which you enjoy.
Always ask what these politicians are proposing. Are they actions going to benefit the rich and powerful or will they promote and give opportunities for the less fortunate to rise.
Finally, make sure these politicians are using sound maths based on facts.
Make sure your choice reflects you spiritual values. Seek and you will find.
The truth you find will set you free.
