In my dreams.
We have similar dreams, but it won't happen in 2012. I'm praying for 2016 - and for an effective effort by her to influence Congressional elections in 2012.
As for a brokered convention, I don't believe it, although it's fun to imagine. Romney would win a deadlocked convention, but the GOP leadership will not permit that. Impatient voters will not permit it either. If a not-Romney can't knock that RINO down before half the races are over, the voters in the second half of the races will line up behind what the party and the mainstream media describe as "Inevitable Mitt". In which case we might as well BOASLAP and BOHICA for Obama.
