You're walking down the street one day when shots ring out at a nearby preschool. You rush in and find two guys standing in there with preschool students as hostages: John McCain and Barack Obama.
Immediately, they turn their guns on you.
"Oh, tough guy, eh? Come in here to save the kids, eh? Think you're a real bruiser, eh?"
"Err, not really, John...well, I heard shots...I guess it would be nice if I could save them."
"Heehee, lookit John, he's scared! Whadda ya think we should do with him, huh? Whadda ya think we should do?"
"Mr. Obama, please, you don't have to do this."
"Ooh, I got it!" *Barack walks over and puts the gun against the head of the nearest preschooler.* "You can decide who's gonna die, tough guy! How about these kids?" *Barack waves his gun at the nearest three children.* "Want them to die?"
*McCain grabs another group of kids.* "Ha! You want them to die? Well, maybe you want THESE kids to die instead!" *McCain waves his gun at the five kids he has before him.*
"Who's it gonna be, tough guy? Who's it gonna be?"
So--who are you going to vote for? The difference here is that only 3 innocent children will die if you go with Obama, rather than thousands.
The difference also is that you have no choice. In the situation above, you have to choose between either Obama or McCain, or else both of them will kill the children. You have no choice except to pick one.
Obama/McCain is like the Green Goblin in the first recent Spiderman movie. They dangle McCain's 100 year Iraq War and greater likelihood of nuclear apocalypse off one side of the bridge, and Barack's slightly lesser likelihood of nuclear apocalypse and increased killing in Pakistan and Afghanistan off the other.
But you don't have to pick one of them. This isn't Spiderman; this isn't preschool hostages. You can refuse to play either of their terrible games. You can resist them.
Most of all, you have the power to give up the deception that Barack Obama is a hero because he might murder fewer innocent people.
