"Political Party" joke

Are you a Democrat, Republican or Southerner?
Here is a little test that will help you decide.
The answer can be found by posing the following
question:
You're walking down a deserted street with your
wife and two small children.
Suddenly, an Islamic Terrorist with a huge knife
comes around the corner, locks eyes with you,
screams obscenities, praises Allah, raises the knife,
and charges at you.
You are carrying a Glock cal 40, and you are an expert shot.
You have mere seconds before he reaches you and your family. What do
you do?
