When I hear somebody call themselves an independent voter in presidential elections I just shake my head. You may think you are choosing the best person available, but in our stinky political system, you are not.
A presidential election is about electing a party to power. If you help elect a republican, thousands of republicans will pour into Washington to steer the Interior Department, Education, etc. etc. in a direction along republican philisophical lines. And then there's the all important Supreme Court and Federal Court appointments, which will also be chosen largely from a pool of party loyalists.
Grow up, dumb ass. Decide whether you are more philisophically aligned with the Dems or Republicans and pull the appropriate lever. Stop all that thinking. It's not a good system, but it's reality.
