I honestly don’t think the people pay that much attention to the politicians they elect. What has been seen after the last election is that the people didn’t get what they thought they would get. The politicians will say anything to get elected. Then, once in office, they put in place policies the people never wanted. Finding honest politicians is the key.
That doesn’t explain why the same politicians get elected over and over. The voters can’t plead ignorance the second time around.
