The last one was in 1948. Wonder if they would try to get someone new in? And who that might be? BO would have to scramble to find some dirt and figure out what kind of strategy to use. http://www.washingtonpost.com/blogs/the-fix/post/how-a-brokered-convention-would-work/2012/01/30/gIQAKTcAfQ_blog.html
The GOP split is more speculative at that point. To see it, letÂ’s examine a map of U.S. counties and how they have voted so far. Blue counties backed Romney, red backed Gingrich, green are for Santorum, while white have gone for some other candidate (or not yet voted). Santorum has more color than the others at this point. http://www.realclearpolitics.com/ar...a_brokered_gop_convention_emerges_113063.html
