"opposite of down?"

I just tried to sign up on your web site--because politically speaking my opinions are Republican, so I wanted to see what's going on with the Republican Party--to be more informed. But I was just surprised that I answered "happy" to the opposite of "down" and the web site said I was wrong--until I went back and put in "sad"---what's up with that?  Not too open-minded to other definitions.

And I really can't believe there aren't better Republican candidates to appeal to more of the mass public. Santorum?  Really?  This can't be the best this party can do.
