http://fivethirtyeight.com/features/when-political-parties-splinter/It's just an interesting political history lesson and consideration drawn to Trump and the effect he might have going forward in regards to the GOP coalition.
If Republican leaders manage to deny him the nomination, we could actually be looking at a split in the party as Trump will no doubt drag voters away from the GOP and cost them one or more elections at all levels of government.
Is it wrong that this level of drama excites me?
