There are 457 unbound delegates going onto the floor in Tampa by design. They are essentially "the Party".
A candidate has to win only about 685 bound delegates and the party can push them over the top.
However, if you read the article and understand it you'll see it's an imminently fair process and count method.
IF you have 685 and another guy has 604 and another guy has 505...you have a brand new hose race on the convention floor.
Folks, you want D R A M A?
Read about the '76 GOP Primary. It's was the last GOP primary to go to the convention floor.
Millions of us dropped to the floor weeping when it was over.
Or the grand fight on the floor of the Cow Palace in '64 when Goldwater won on the first ballot. There were fist fights in the aisles!!
Now imagine these things in the modern TV/Internet era.
Simply wow.
They be breakin’ them cellphones on they haids!
