Your post saying it was a little early to call it was at 9:20. By that time well over 90% of the vote was in and the state was long since called for Willard. With 98% in, Romney got 57%, Gingrich 27%, Paul 10%, Santorum 6%. It was an easy call for the networks to make since it wasn't even close.
But however they manage it, I still will not vote for Romney. There will be a conservative on the ticket.
