what exactly does that mean?
What it means is that no candidate has a majority of delegate votes at the convention, so the nominee is then decided through horse-trading with delegates released from their previous obligations.
The HUGE weakness to this type of convention is that it leaves the door open for Romney, which is a fate worse than death both to me and to the GOP.
The advantage, and it may be all conservatives have, is that it’s possible a real conservative candidate might emerge.
