At a brokered convention, Palin would come in just after Joe Lieberman with the rank and file and the elites of the party. The Powers That Be have been ripping her for four years, they aren’t going to pick her now.
Funny you should mention that. John McCain wanted Joe as his running mate in 2008 and had to be talked out of it by his staff. Then Bill Kristol talked up Sarah Palin.
