Saying those posters were "right" is like saying a guy who always claims the next card pulled from a deck will be the ace of spades is right when that card is finally pulled after 30 others. No one "knew" a year and a half ahead what would happen in that race, they took countless stabs in the dark and one stuck. Grow up.
I had predicted at every single point since I came to this forum that Santorum would lose in 2006, and much time before that. I never at any point believed Santorum would win. Was I wrong?
