On what basis should we choose who to vote for? In short, it's best not to vote on the basis of tradition, promises, what benefits us personally, what others think, or what may seem rational at the time on the basis of public media reporting.
Our decisions are more wisely made on the basis of two things: the actual policies of the political parties, and the moral character of the politicians. These two things are like the ink of the pen that writes our future!
