Are you for real?
First of all, to say that they are all liars is the laziest way to go about this. This is an evolution vs creation debate forum. We see this kind of lazy thinking all the time.
A horse can move from point A to point B 2 miles away. A car can do the same thing. A car must be the same as a horse.
Oh, how about this. Don't tell me you've never lied before in your life. If you've ever lied, then technically you are a damn liar. Hitler was a liar, too. You must be on the same level as hitler.
Have you ever eaten chicken? Sure you have. My dogs love to eat chicken. You must be the same as my dogs.
You are down playing how shamelessly a liar Romney is by saying they're all liars and therefore they are all the same.
But more importantly, when you made the statement that Obama hasn't kept some of his promises, you're assuming we elected him as the absolute emperor dictator of the country.
Repeat after me, we didn't elect Obama to be the absolute dictator emperor of our country.
Since you've eaten chicken and my dogs also have eaten chicken, you must be the same as my dogs. I don't suppose you want to play catch with me?
