There won’t be a brokered convention if Newt’s presence splits the vote.
I see it exactly opposite- Newt will split the vote, stopping Romney from getting a majority, confining him to less that 50%, and causing an open convention, where God only knows what will happen. If Newt were to get out now, Romney will bulldoze Santorum, and go on to lose to Obama. Just like Gerald Ford, Bob Dole, GHWB, and John McCain. Is there something that keeps Republicans from learning from past fiascos?
