You have to change the voters’ minds. There are just enough delegates left that Newt potentially could take it if he sweeps it, however, that chance is almost zero. Get out there to the remaining states and educate voters. Simple as that.
You probably could fit all the Newt supporters in CT in a phone booth—if they are any still around (newt supporters or phone booths). :-)
Newt isn’t counting on sweeping it.
He’s trying to deadlock the convention, and he’s trying to qualify to be a force there.
