Dixie, if you express an opinion in which you state that you think this, or that, will occur, it is a prediction
In your example...
"A. I predict the Democrats will not be able to govern from the center.
B. I don't believe Democrats will be able to govern from the center. "
B is still a prediction, even if you qualify it with the word 'believe'
You are predicting that, according to your belief, the Dem won't etc etc....
If you get BILLO in another 100 post rant about whether or not his predictions are or are not predictions (and from my experience they are when he is right and aren't when he is wrong) I will have to find something else to do today.
