I do appreicate your chart, but those polls are going to change. No one has broken away from the pack yet. I’m willing to bet that candidates like Huck and Carson are not going to be in the upper tier come fall.
I watch it daily and it changes slightly. Most recently Perry has come up slightly and Trump down. There used to be a larger gap between them. But it is sure to change dramatically. There is no saying when but it will happen.
