Why am I independent? Because I dont want to identify myself with a party. I feel like it would be a flaw for me to possibly become emotionally attached to one side and have it cloud my judgement. I also would rather judge candidates as individuals. Their political views are of equal importance to me as how I judge their character as a person, even if all politicians are liars.
And, sorry to drag religion in, but its important too. I am Buddhist and believe all life is suffering. Politics seems to be the epiphany of suffering. I can at least choose which individual will be the least excruciating of choices. You can see why I dont want to closely affiliate with such sufferable people.
